ensure! now rechecks trigger presence under BEGIN IMMEDIATE, backfills
drifted rooms.messages_count, and reinstalls all three triggers before
commit so concurrent writers and concurrent boot repairs cannot observe
a partial install or keep a wrong total. install! uses the same
immediate write lock for drop/recreate. Lifecycle regressions cover
missing/partial trigger drift, concurrent ensure!, and writes racing
repair.

X-Total-Count on GET /rooms/:id/:bot_key/messages was COUNT(*) of the

ActiveRecord counter_cache callbacks those paths skip.

Banning a user deletes their sessions and closes their connections but
keeps their push subscriptions, and Room::MessagePusher chose recipients
by membership alone. A banned user's browser or phone therefore went on
receiving the room name, sender and text of new direct messages,
mentions, and messages in rooms they had set to everything.
Choose subscriptions from active users only. The subscriptions are kept,
so unbanning brings notifications back without the user having to
subscribe again (the client doesn't resubscribe while the browser still
holds a subscription).

Transfer the C completed-response cache lesson into Rails, keeping authentication, room checks and cookies per request. A persistent read-only SQLite observer detects local and foreign commits and rejects racing admission. Whole-page misses render fresh to avoid stale nested fragments; message ETags reflect token-neutral presentation.
* Derive message DOM ids from the server id, not client_message_id
A message's DOM id was derived from the browser-chosen client_message_id
via a Message#to_key override, so dom_id(message) was
"message_<client_message_id>". Turbo's append de-dups by DOM id, so a room
member who posted a message reusing a victim's client_message_id displaced
the victim's message element in every connected member's live view; editing
the attacker's own message then broadcast onto the victim's presentation id.
Drop the to_key override so every message DOM id and broadcast target derives
from the record's primary key. Two distinct records can no longer share a DOM
id regardless of stored client_message_id, so the collision is impossible with
no data migration and no uniqueness constraint. to_param and the fragment
cache key already used the primary key, so message URLs and per-message cache
entries are unchanged.
The composer's optimistic pending message still uses client_message_id as its
placeholder DOM id, which no longer matches the server broadcast's PK-based id.
Reconcile instead by rendering data-client-message-id on the real message and
having the messages controller drop the matching pending placeholder on
connect. Only client-side placeholders (data-pending-message) are removed, so a
message another member posts reusing the same client_message_id can never
displace a real one through the reconciliation path either.
Also point the boost broadcast target at the PK-based dom_id(message, :boosts)
to match the rebuilt container id.
GHSA-3v99-4vxh-xg84
* Bust cached message fragments rendered with client_message_id DOM ids
The message fragment cache keys on the record and the template digest, and
removing the to_key override changes neither. Fragments cached by an earlier
release would keep their message_<client_message_id> ids, so edit, delete and
boost broadcasts, which now target primary-key ids, would miss those messages
in other members' live views until the cache entry expired.
* Locate messages by record id in the client_message_id collision tests
Assert on data-message-id rather than the new primary-key DOM ids, so the tests
describe the behavior instead of the fix and fail on the vulnerable code for the
real reason. Edit the attacker's message to new text and wait for it to arrive,
so the edit path is exercised rather than passing vacuously. Add a request test
that two messages sharing a client_message_id render as distinct elements.

The Rust port creates index_messages_on_room_id_and_created_at on boot,
under the same name and on the same columns, with CREATE INDEX IF NOT
EXISTS. On a database the port opened before this migration ran,
db:prepare stopped with "index ... already exists" and the app didn't
start. With if_not_exists the migration skips an index that is already
there and creates it everywhere else.
Databases that already ran the migration don't run it again, and the

Showing an image's preview when its variant had already been made tied the cached message to state
that changes without touching it: a variant made after the message was cached would never show. It also
cost a query per embedded image, since Action Text loads the embeds without their variant records.
Nothing in the app makes those variants, so the partial no longer looks at them.

Files are posted as a message's own attachment, and the composer puts none in the rich text: it permits
only mentions and link embeds. The server still keeps any attachment whose signed id resolves, a blob
included, and Action Text's blob partial links to a representation URL that makes the preview on the
first request, without the limits the POST has, and on every request while it fails.
The app's own partial shows an image's preview only if it was already made, and otherwise the file's
name and size, as it does for a file that isn't an image. The cached presentation's version goes up,
since Action Text renders the partial by name and the template digest doesn't see it.

ActiveStorage::Preview#processed? is true as soon as ffmpeg's frame is attached, but the poster is a
variant of that frame and can fail on its own: the POST rescues a Vips::Error and leaves the frame
attached. The view then emitted the poster's URL, and every view retried the resize. It now checks the
variant too, from the variant records with_attached_attachment already preloads.

A video's preview and a picture's thumbnail are made inside the request that posts the message, and
nothing bounded how long either could take.
- The video preview filter also selects any frame from 5 seconds on. Rails' filter takes the second
frame it selects, which a video with a single keyframe and no scene change only gives at its end, so
ffmpeg decoded all of it.
- TimeLimitedVideoPreviewer gives ffmpeg 10 seconds of wall-clock time, kills it past that, and reports
a failed preview, so the message is posted without one.
- Pictures and videos above 250 megapixels, or whose size couldn't be read, get no preview: decoding
costs in proportion to the pixels, however small the file.
- The view shows a preview only if it was made when the message was posted. Its URL used to make it on
view, so a preview that failed or was skipped would be attempted again on every view. The cached
presentation's version goes up, so cached messages pick this up.
- A video's poster is made, when the message is posted, at the size the view shows it. The full-size WebP
made until now wasn't shown anywhere, and encoding it costs in proportion to the frame's pixels.

Deleting the memberships with delete_all skips Membership's after_destroy_commit, which resets a member's
connections when one membership is revoked. Until the job ran, a member who had the room open kept its
streams, and a message that still landed in the room (a request already past the membership check, a bot's
reply) reached them. The request now reads the members' ids in the transaction that deletes their
memberships, and the job resets their connections before it destroys the messages. It costs a Redis round
trip per member, about 1.5 s for 10,000, so it's done in the job rather than in the request.
User#grant_membership_to_open_rooms read the open rooms and inserted in a separate statement, so a user
created while a room was being closed could read it as open and be granted it after the close. It's now a
single insert ... select, which SQLite runs under the write lock, skipping duplicates as insert_all did.

The deadline in Opengraph::Fetch started after the lookup of the pasted

Room#destroy destroyed every message inside the room's own
transaction, which holds SQLite's write lock until the last one: on a
room with many messages, every other write in the app waited and
failed. The request now takes the room away from its members and
leaves the rest to Room::DestroyJob, which destroys the messages one
at a time, each in its own short transaction, and then the room.
An open room is closed in the request, so that someone who joins the
account before the job ends isn't given it.

Opengraph::Fetch runs inside POST /unfurl_link, against a host the member
picked, with Net::HTTP's defaults: 60 s to connect, 60 s for each read, and
one retry of the GET. A per-read timeout doesn't bound a host that sends a
byte at a time, in its headers or its body, so nothing limited how long a
fetch could hold the request thread.
Give each operation 7 s, as Webhook does, turn off the retry, and put the
whole fetch, redirects included, under one 10 s deadline.

Only a failure while Net::HTTP checks a reused idle socket means the
push service closed it, and a new connection can take the push. A
failure while connecting again, such as a certificate for another
name, or before the request is written on a new connection, is raised
as it is, so the subscription is invalidated as before. After the
request is written, a dropped connection raises ConnectionLost on new
connections too.

Since push delivery was pinned to the IP resolved and guarded for it,
every push opens a new TCP and TLS connection: Net::HTTP::Persistent
looks the host up itself and can't be pinned. The handshake is one or
two extra round trips for every push.
WebPush::Connections keeps the pinned connections open for 30 seconds
and hands one out again only to a delivery whose own, fresh resolution
returned the same address for the same host. Net::HTTP only ever
reconnects to that address, so no request goes to an address the guard
didn't just approve. A connection the push service closed while idle is
replaced before the push is written; once it's written, a dropped
connection raises ConnectionLost instead of sending the push twice or
invalidating the subscription. A delivery without a resolved IP is no
longer sent at all, and net-http-persistent goes.

Rails 8.2 compiles HTML templates through Herb in strict mode, so a
template that doesn't compile fails to render. herb:check boots the app,
which loads ruby-vips, hence libvips.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Rails main (e3d5c569) moves Campfire's pin forward ten months. Because
Campfire loads the 8.2 framework defaults, the ones added since then take
effect too, among them header-only forgery protection, Herb as the HTML
template engine, strict Accept headers and immediate blob analysis.
Changes it needed:
- Minitest 6 has no minitest/unit; the test helper no longer requires it.
- Rack::Sendfile is no longer in the middleware stack; DebugLocks goes
before ActionDispatch::Executor, as the Rails guide now says.
- Time::DATE_FORMATS is deprecated; :epoch is registered through
ActiveSupport::TimeFormats.
- Channel test subscriptions expose stream_names; streams is private.
- sentry-rails declares its Action Cable handle_open and handle_close
wrappers private, which Rails 8.2 calls from outside the connection, so
no /cable connection succeeded. An initializer makes them public until
getsentry/sentry-ruby#2972 ships (issue #2975).
- Lexxy renders editor content through Rails' editor adapter when Rails
has one, which asks a mention for its editor partial. It is the same
users/mention partial the mention prompt already inserts.
- redis-client moves to 0.30.1: Rails main's Redis cache store, which
production uses, requires 0.28.0 or later, and assets:precompile
(the Docker build) aborted on 0.25.2.

(cherry picked from commit b4d3880a3d88059dd5b0b884f1f5f1a6f82aa95c)
Rails main compiles HTML templates through Herb under the 8.2 framework
defaults, which Campfire loads. Herb rejects `case` and its first `when`
in a single ERB tag, so the three pwa/ partials failed to compile, and
`herb:check` rejects ERB output in attribute names, which the account
settings' switch used for `checked`. Give `case` its own tag and build
the switch with tag.input; both render the same under Erubi.

Each push notification carries the subscriber's unread room count as its
badge. The pool built it per subscription, loading the user and counting
their unread memberships: two queries for every subscriber, all in the job
before the deliveries reach the threads. With 1,000 subscribed members the
job spent ~180 ms and 2,000 queries there; with 5,000, a second.
The pool now counts the unread rooms of a whole batch with one grouped query
and hands each subscription its badge; nothing else in the notification needs
the user. The queries still run before the work is posted to the threads,
which run outside the Rails executor. Push::Subscription#notification still
counts by itself when no badge is given, as for the test notification.

Every boost had its own fragment, nested inside the message fragment that
already holds it. With a cold cache, a read and a write per boost plus a
read_multi and a write_multi per message: a room page of 40 messages with
120 boosts takes ~410 ms instead of ~290 ms. Redis runs without persistence
(config/redis.conf), so every page is cold after a restart.
A boost touches its message, so adding or removing one rewrites the message
fragment anyway. The inner fragments only paid off when a message with many
boosts was drawn again, and there they hid a lookup per booster. The boosters
are now loaded with the boosts, one query per message.

The job picks the room's members once and then publishes to them one at a
time, as the request did before it. A member who opens the room during that
loop gets the read event in their other tabs and then the older notice,
which marked the room unread again. Both events now carry the server time,
and the sidebar ignores a notice dated before the room's latest read. The
notice still moves a direct room to the top.

Every room visit and every reconnection asks for the messages updated
since the page was rendered. That query filtered the room by updated_at
and sorted it by created_at, so SQLite walked every message in the room:
about 220-360 ms in a room of a million messages. An index on
(room_id, updated_at) finds the few updated messages directly.
Sorting on +created_at keeps SQLite on that index once messages are also
indexed by (room_id, created_at): with both, the planner otherwise walks
the room in creation order looking for updated rows.

Opening a direct room looked for an existing one by loading every direct
room on the account and comparing its member ids in Ruby, two queries per
room, on each click. The cost grows with the account: about 0.3 s at 1,000

Now that the unread fanout runs in a job, it can run after a member has

then mark the room unread for a message they have seen.
The job now notifies only members who still have the room unread or are

The composite index doesn't serve everything the room_id one did. In
SQLite that index is (room_id, rowid), so it also reads a room's messages
in id order, and it is the narrower one to count a room with. Keeping both,
as memberships already does, leaves those lookups as they were.
The migration was named after local time, two hours ahead of the UTC

Since the unread rooms stream was scoped per user, posting a message
publishes the room id once to each member of the room. Each publish is a
round trip to Redis, made one after another inside the request, so the time
to post a message grows with the size of the room and in a big room is far
more than the rest of the request.

Every page of a room's messages (opening the room, scrolling back, the
refresh after reconnecting, the bot API) selects WHERE room_id = ? ORDER BY
created_at LIMIT 40. With only the room_id index, SQLite reads every
message in the room and sorts them in a temporary B-tree to return 40, so
these requests grow with the room's history.
A composite index on (room_id, created_at) lets SQLite read the 40 rows in

The composer editor carries the lexxy-content class, so the !important
list rules for message bodies hit the menu's ul and li too, leaving the
items cramped and pushed in from the left.
The editor keeps an attachment's content as it finds it, so a hand-written
embed with a url but no href reached the editor with its markup unvalidated,
and a mention saved under Trix's editor carried the generic octet-stream
content type the editor doesn't permit and was dropped on save. Rebuilding
each attachment from its attachable renders the hardened preview partial
and restores the mention content type.
Main strips a javascript: href from a preview node before it's parsed, so
tell legacy Trix attachments apart by their filename instead. escapeHTML
moved to the string helpers, and the unfurling system test now drives
the Lexxy editor.
The companion to #279: the same per-instance `extend` appeared in
test/lib/rails_ext/action_text_attachables_test.rb. `attachable_sgid` is
`to_sgid(expires_in: nil, for: ActionText::Attachable::LOCATOR_NAME).to_s`,
so mint that directly; the minted bytes and the assertion are unchanged.

Agent worktrees under .claude/worktrees are whole extra checkouts of
this repo, and the build context picks them up. .claude is local
session state and never belongs in an image.
Moves the pin from the pre-release 910be91 (0.1.0) to 59e278c, the v0.2.0
tag Fizzy already runs. The default policy now admits IPv6 only inside
IANA-allocated unicast prefixes instead of default-allowing reserved and
unallocated space. No call-site changes: both shim entry points take the
new policy keyword's default.
The invalid-sgid test made one live Room attachable — `rooms(:pets).tap
{ |r| r.extend ActionText::Attachable }` — only to call
`attachable_sgid` on it. That method is `to_sgid(expires_in: nil,
for: ActionText::Attachable::LOCATOR_NAME).to_s`, so the test can mint
the same sgid directly and drop the per-instance extend; the assertion
(a signature that does not verify resolves to MissingAttachable) is
unchanged, and so are the bytes it tampers with.
Link previews fetch a page's OpenGraph title and description, and
Opengraph::Metadata strips tags from both before the values reach the
browser. When a field consists entirely of a markup tag, stripping
leaves it blank, the metadata fails its presence validation, and the
unfurl endpoint returns no content, so no preview is produced.
Add regression tests at the model and controller layers that pin this:
a title or description made only of a markup tag is stripped to blank
and rejected, and the endpoint answers 204. The existing sanitize tests
only cover fields that keep non-blank text after stripping, so this
blank-and-rejected path was previously untested.

There were two: the one in dom_helpers escaped through a text node, which
leaves double quotes alone, so it could not have closed the hole in the
link preview's img src.

Pasting a link builds the preview by interpolating the unfurled metadata
into an HTML string. The image URL went into src="..." unescaped, so a
page whose og:image carries a double quote closes the attribute early and
everything after it becomes attributes on the preview's img element.

A domain name ends in a word, which is what keeps it from reading as an
address. "0x7f.0.0.1" carries a dot and a letter, so the previous shape
check let it through while a browser fetched 127.0.0.1.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_0186eyzivcTn6wqjEE4Wnxdt
A browser rewrites the many spellings of an address into one before it
fetches, so "http://2130706433/rooms/1" arrives at 127.0.0.1 while a
comparison here still reads the digits. A preview names a page on the
public internet, so require its host to look like a domain name and leave
the rewriting race alone.

The room caches each message's rendered presentation, and its key can't
see the link preview partial, which ActionText renders by name rather than
through a render call the digestor can follow. Without a new version, a
message already in the cache would keep its old preview.

Ruby leaves a percent-escape in URI#host, so "https://%77ww.example.com"
read as a different host than the one Campfire answers on while a browser
unescaped it straight back to us. A host that carries an escape, or a
trailing dot, is now measured the way the browser will read it.

A preview belongs to the page it previews, so both URLs point somewhere
else. An absolute URL on our own host passed the scheme and host checks,
and every reader's browser fetched it with their session attached, which
turns a message into a GET request made on the reader's behalf.

Ruby parses "https:/rooms/1" as an HTTPS URL with no host, and a browser
resolves it against whatever origin Campfire is served from, so the scheme
check alone still let a message body aim the preview at a path here.

A link preview's link and image come from attributes on the message body,
which the composer fills in from the unfurl the server performed. A body
written by hand can put anything in those attributes, and the preview
partial rendered them as they were.
Keep the link and the image only when they parse as absolute http or https
URLs, so nothing in a message body can aim either one at another scheme or
at a path on this Campfire, and render the title and the description as
text.

The bot HTTP API carries the bot key as a URL path segment
(/rooms/:room_id/:bot_key/...). config.filter_parameters redacts query
and form parameters but never path segments, so the key was written
verbatim to the request log (the "Started POST ..." line) and to any
log line echoing the pagination Link header.
Add a log formatter that redacts the bot-key path segment wherever it
appears in a formatted line, and wire it into the production logger.
Action Cable authorizes a Connection once at the WebSocket handshake and
never re-checks it. Destroying the session record refuses future handshakes
and HTTP requests bearing the cookie, but a socket opened before sign out
keeps its handshake-time current_user and keeps authorizing new
subscriptions and delivering frames as the signed-out user.
Reset the user's remote connections when the session is terminated. Clients
tear down and reconnect: the signed-out device carries a destroyed session
and cleared cookie and is rejected at the fresh handshake, while the user's
other devices with still-valid sessions reconnect and stay live. This reuses
the existing reset_remote_connections primitive already used on membership
removal, for the same reason.
Run the disconnect last and best-effort, after the session record and cookie
are already gone, so sign out completes even when the realtime service is
unreachable.
Active Storage mounts its direct-upload write endpoints -- POST
/rails/active_storage/direct_uploads and the disk-service PUT at
/rails/active_storage/disk/:token -- on framework controllers that inherit
from ActiveStorage::BaseController, so they never pass through
ApplicationController's require_authentication. Anyone who can read the
public login page can lift a CSRF token and Rails session cookie, POST to
the metadata endpoint, and receive a signed disk PUT URL without holding a
Campfire session_token.
That is enough to allocate ActiveStorage::Blob rows and persist bytes to
disk anonymously. The blobs stay unattached (no message can be created
without an account) and nothing purges them, so an unauthenticated caller
can grow storage without bound. Because the recommended self-host layout
co-locates uploaded files and the SQLite database on one /rails/storage
volume, that growth eventually makes database writes fail -- blocking login
and messaging until an administrator frees space and purges the blobs.
Campfire uploads attachments through MessagesController as a normal
multipart POST and does not use direct uploads at all, so these endpoints
have no legitimate anonymous caller. Require a valid Campfire session
before the metadata endpoint allocates a blob or the disk endpoint accepts
an upload; both return 401 to anonymous callers. Serving (disk#show,
representations, blob redirects) is unchanged.
* Guard push-subscription endpoints against SSRF
Web push delivery POSTed to the endpoint URL a user supplied when
registering a subscription, with no scheme, host, or private-network
check -- unlike the OpenGraph unfurl path, which already routes through
the shared SSRF address policy (surfguard). Any authenticated user could
register a subscription whose endpoint pointed at an internal address and
have the server fetch it on every chat message: blind SSRF for internal
recon and reachability probing, plus a thread-pool DoS on the delivery
pool.
Validate the endpoint when the subscription is saved: it must be HTTPS,
its host must belong to a known browser push service (allowlist), and it
must resolve to a public IP. On every delivery, re-resolve the host and
pin the connection to that public IP so a later DNS rebind can't redirect
the request to an internal address. If no public IP resolves at delivery
time -- a rebind, or a subscription that predates this validation --
delivery is skipped rather than falling back to re-resolving the raw
host.
Adds model, controller, and delivery-pinning tests, plus a DNS stub
helper for deterministic resolution in tests.
* Route push endpoint guarding through RestrictedHTTP::PrivateNetworkGuard
The endpoint SSRF check already delegated its private-network classification
to surfguard, but called Surfguard.resolve_public_ips directly rather than
through RestrictedHTTP::PrivateNetworkGuard -- the hostname-in, address-out
shim #241 established as the app's single guarded-outbound entry point and
that Opengraph::Fetch resolves through. Route push resolution through the same
guard so once-campfire keeps one place that resolves and classifies outbound
addresses. Behavior is unchanged: the guard raises Violation when a permitted
host resolves only to blocked addresses (previously an empty list -> nil) and
propagates Surfguard::Unresolvable for a host that resolves to nothing; both
map to a nil endpoint IP, which fails validation and skips delivery. The
allowlist, HTTPS/443 constraints, and per-delivery IP pinning are unchanged.
* Address push-SSRF review: defer DNS off enqueue path, disable proxy on pinned path, revalidate on re-registration
- Resolve the guarded endpoint IP lazily inside WebPush::Notification#deliver
(on the bounded delivery worker) instead of eagerly when the notification is
built on the serial enqueue path, so a slow resolver can't stall the push job
before any delivery starts. resolved_endpoint_ip only reads the already-loaded
endpoint attribute, so it is safe off the AR connection.
- Pin the delivery socket with an explicit nil proxy address so http_proxy/
https_proxy can't route the request through a proxy that re-resolves the host
and defeats the ipaddr pin.
- Revalidate an existing subscription on re-registration so a row predating
endpoint validation gets the same 422 as a fresh create instead of being kept
alive by touch.
- Regression tests: resolution deferred to delivery, pin survives proxy env,
legacy invalid row rejected with 422.
* Bound the web-push delivery queue (max_queue, not the ignored queue_size)
Concurrent::ThreadPoolExecutor takes :max_queue; :queue_size was silently
ignored, leaving the delivery backlog unbounded (max_queue: 0). A flood of
valid push subscriptions could accumulate queued deliveries without limit --
more acute now that each delivery task also resolves DNS. Using max_queue: 10000
activates the intended cap; overflow raises RejectedExecutionError under the
default :abort policy, which deliver_later already rescues (push is best-effort,
retried on the next message).
* Trim push-SSRF guard comments to match house style
Apply the review suggestions on the push-subscription SSRF guard: replace
the verbose rationale comments with terse one-liners (or drop them where
the code speaks for itself). No behavior change -- the Surfguard-shim
routing, per-delivery public-IP pin, and bounded delivery queue are
untouched.
Three pins, two values: Dockerfile said 3.4.5, Dockerfile-export said
3.4.7, .ruby-version said 3.4.5 — the export image had already been
bumped on its own and nobody noticed the other two lagging. Both
Dockerfiles carry a comment telling you to keep them in step.
3.4.10 is the current 3.4.x. CI resolves its Ruby from .ruby-version,
so this is the version the tests now run under.
v1.295.0 predates Ruby 3.4.10 — its baked-in version index stops at
3.4.9, so asking for anything newer fails with "Unknown version 3.4.10
for ruby on ubuntu-24.04". The next commit needs 3.4.10, and pinning
our Ruby to whatever an old action happens to know is backwards.
SHA verified against the v1.321.0 tag.
The base image tag is a build arg — `ARG RUBY_VERSION` plus
`FROM ruby:$RUBY_VERSION-slim` — and Dependabot's docker updater matches
literal tags, so this entry has never had anything to propose. It ran
green every week and reported nothing, which reads as coverage and
isn't.
No other repo in the fleet configures a docker ecosystem, and none
could: they all either interpolate a variable or pull from the internal
registry. Inlining the tag here to buy coverage would make this
Dockerfile the outlier instead, against Rails-generated boilerplate.
Ruby bumps stay a manual, human-decided step.
The docker block copied bundler's cooldown wholesale, but Dependabot only
accepts semver-major/minor/patch-days for ecosystems whose versions it
classifies as semver, and container tags aren't. One invalid property
invalidates the entire file rather than the block it sits in, so since
this config landed in #248 the version updater has not run for any
ecosystem at all:
Your .github/dependabot.yml contained invalid details
The property '#/updates/2/cooldown/semver-major-days' is not supported
for the package ecosystem 'docker'. (and -minor-, -patch-)
That is why #249's cooldown exclude for brakeman never took effect, and
why #250 had to bump the workflow linter pins by hand while every other
repo got a Dependabot PR. It also left `bin/brakeman --ensure-latest 15`
armed with nothing to disarm it: the lock pins brakeman 8.0.6, and CI
would have gone red roughly 15 days after 8.0.7 shipped.
Security updates were never affected — those don't read this file, which
is why the only four Dependabot runs here are single-gem security bumps.
docker keeps default-days, which is supported for every ecosystem.
Dependabot version updates are disabled for this repo, so the weekly
github-actions group never proposed these. The pins had been frozen since
March: zizmor-action v0.5.2 ships zizmor 1.23.1, which flags
secrets-outside-env at the default persona -- that moved to the auditor
persona in zizmor 1.24.0. v0.6.2 ships zizmor 1.29.0.
Both linters pass locally at the new versions.
* Take the SSRF address policy from surfguard instead of keeping our own copy
Four other apps carried this same classification and the five had drifted into
four different ideas of what "internal" means. It now comes from the surfguard
gem, which is their union. resolve and Violation keep their shapes, so the
opengraph callers are unchanged.
Two verdicts change.
SIIT (::ffff:0:0:0/96) is now recognised. It is the third way an IPv4 address
rides inside an IPv6 one and the only one Ruby has no predicate for --
ipv4_mapped?, ipv4_compat?, private?, loopback? and link_local? are all false
for ::ffff:0:a9fe:a9fe, so it fell through to the IPv6 branch unrecognised and
reached the metadata endpoint. Note the extra group: ::ffff:0:0:0/96 is not the
IPv4-mapped ::ffff:0:0/96 the guard already refused, and the two do not overlap.
The RFC 8215 local-use NAT64 block is now refused whole rather than decoded.
Reading its low 32 bits as an embedded IPv4 is only correct for a /96 Pref64;
the block can host any length from /32 to /96 and the position is not
recoverable from the address alone (RFC 6052 2.2), so the decode reads the
wrong octets. It is never globally routed, so refusing it costs nothing. The
well-known /96 is still decoded and re-checked, so DNS64 for public sites on
IPv6-only hosts keeps working.
Resolution moves from Resolv.getaddress to Resolv.getaddresses, so the guard
sees every address a host answers with rather than only the first.
* Distinguish a DNS lookup failure from a private-IP block in the guard
Advance the surfguard pin so resolve_public_ips raises Unresolvable when a
host resolves to nothing and returns an empty list only when it resolves to a
blocked address. The shim lets Unresolvable propagate as a lookup failure --
matching the old Resolv.getaddress behavior -- and reserves Violation for a
resolved-but-blocked address, so a transient DNS miss is no longer reported as
an SSRF attempt.
* Bump brakeman to 8.0.6
Brakeman 8.0.6 shipped 2026-08-12: corrected Rails 8.0 EOL date, added
Rails 8.1 and Ruby 4.0 EOL dates, and fixed command-injection false
positives.
brakeman's only runtime dependency is racc and its required ruby is
>= 3.2.0, both unchanged since 7.1.2, so this is a version bump with no
other movement in the graph.
* Give brakeman's --ensure-latest a 15-day grace period
Bare --ensure-latest exits 5 the moment a newer brakeman exists, so a
release turns this build red before anyone has a chance to react. That
is what happened on 2026-08-12 when 8.0.6 shipped.
The flag takes an optional minimum age in days and only complains once
the latest release is at least that old. 15 is the maximum it accepts;
brakeman rejects anything outside 1-15.
* Exempt brakeman from the dependabot cooldown
The grace period on --ensure-latest is only headroom if the bump lands
inside it. A weekly schedule plus a 7-day cooldown can take 14 days to
so much as open the PR, leaving a single day to merge it.
Excluding brakeman from the cooldown caps the delay at the weekly
schedule, comfortably inside the 15 days.
The advisory (email address spoofing via malformed RFC 2047
encoded-words, CVE-2026-63435) landed in ruby-advisory-db on
2026-08-18, turning the gem audit red since the audit pulls a live
advisory DB. 2.9.1 is the patch release for exactly this CVE.
Bots can only create. A lifecycle notification — an alert that fires and then
resolves, a deploy that starts and finishes, a backup that runs — therefore has
to post a second message, and the room becomes an append-only log of states
rather than a view of the current one.
Adds PATCH and DELETE inside the existing bot_key scope, routed to
Messages::ByBotsController. The body is read the way create reads it, so
updating a message is the same request shape as posting one.
No new authorization: both actions already run through ensure_can_administer,
and can_administer? grants access only to a record the user created, so a bot
key reaches that bot's own messages and no others. set_room narrows it again by
looking the room up through the bot's own memberships. A leaked bot key gains
what it could already do by posting: write to rooms that bot belongs to.
update answers head :ok rather than the redirect, which meant extracting the
update and its broadcast into update_message — calling super and then head
would double render, since the parent redirects inside the action. destroy
needs no split, because the parent renders implicitly like create does.
- Use jbuilder instead of hashes
- Use resource instead of direct HTTP verbs
Verbs only make sense if you have one or two routes, if there are
multiple that emulate what resource does then it's better to use resource.
- Paginate using link headers
- Cache responses
Adds a new endpoint that allows bots to add emoji reactions (boosts) to messages:
POST /rooms/:room_id/:bot_key/messages/:message_id/boosts
This enables bots to acknowledge messages with reactions like 👀 (eyes) when
mentioned, providing immediate feedback to users before generating a full response.
The endpoint:
- Validates the bot is a member of the room
- Validates the message exists in the room
- Broadcasts the boost to connected clients via Turbo Streams
- Returns 201 Created on success, 404 if room/message not found

Fixed test bug identified by Copilot code review: pagination tests were
using Message.first and Message.last which could return messages from
different rooms than the test's @room (watercooler).
Now explicitly using messages(:fourth) and messages(:thirteenth) which
are fixtures belonging to the watercooler room where bender bot is a member.

Both create and index now return HTTP 404 Not Found when a bot tries to
access a room it's not a member of. This is consistent with REST API
security best practices (not revealing resource existence) and ensures
read and write permissions are handled identically.
Changed create action to no longer call super (which rendered HTML) and
instead directly handle the request with proper JSON API error responses.
Added test to verify create returns 404 for non-member rooms.

Added explicit RecordNotFound handling to return 404 when a bot tries to
read messages from a room it's not a member of. This matches the security
model used by the create action.
Added tests to verify:
- Bot gets 404 when trying to read from room it's not a member of
- Bot can successfully read from room it IS a member of
Co-authored-by: openhands <openhands@all-hands.dev>
Adds a new GET endpoint at /rooms/:room_id/:bot_key/messages that allows
bots to read messages from rooms they are members of.
The endpoint returns JSON with:
- Room info (id, name)
- Messages array with body (plain/html), created_at, and creator info
- Pagination info (oldest_id, newest_id, has_more)
Supports pagination via ?before=:id and ?after=:id query parameters,
consistent with the existing pagination in the messages controller.
This enables AI bots and other automated agents to understand conversation
context when responding to messages, rather than only receiving the single
message that triggered the webhook.
