f9b7b65371 fix(security): enforce wiki git writes and LFS token access at request time (#37695)
This PR fixes two permission-checking gaps in Git and LFS request
handling.

## What it changes

- keep wiki Git HTTP pushes on the normal write-permission path, even
when proc-receive support is enabled
- revalidate LFS bearer token requests against the current user state
and current repository permissions before allowing access
- add regression coverage for unauthorized wiki HTTP pushes
- add LFS tests for blocked users, revoked repository access, read-only
upload attempts, and valid write access

## Why

- wiki repositories should not inherit the relaxed refs/for handling
used for normal code repositories
- LFS authorization tokens should not remain usable after a user is
disabled or loses repository access

db7eb4d51b Fix issue label deletion with Actions tokens (#37013)
Use shared repo permission resolution for Actions task users in issue
label remove and clear paths, and add a regression test for deleting
issue labels with a Gitea Actions token.

This fixes issue label deletion when the request is authenticated with a
Gitea Actions token.
Fixes #37011 

The bug was that the delete path re-resolved repository permissions
using the normal user permission helper, which does not handle Actions
task users. As a result, `DELETE
/api/v1/repos/{owner}/{repo}/issues/{index}/labels/{id}` could return
`500` for Actions tokens even though label listing and label addition
worked.

45809c8f54 feat: Add configurable permissions for Actions automatic tokens (#36173)
## Overview

This PR introduces granular permission controls for Gitea Actions tokens
(`GITEA_TOKEN`), aligning Gitea's security model with GitHub Actions
standards while maintaining compatibility with Gitea's unique repository
unit system.

It addresses the need for finer access control by allowing
administrators and repository owners to define default token
permissions, set maximum permission ceilings, and control
cross-repository access within organizations.

## Key Features

### 1. Granular Token Permissions

- **Standard Keyword Support**: Implements support for the
`permissions:` keyword in workflow and job YAML files (e.g., `contents:
read`, `issues: write`).
- **Permission Modes**:
- **Permissive**: Default write access for most units (backwards
compatible).
- **Restricted**: Default read-only access for `contents` and
`packages`, with no access to other units.
- ~~**Custom**: Allows defining specific default levels for each unit
type (Code, Issues, PRs, Packages, etc.).~~**EDIT removed UI was
confusing**
- **Clamping Logic**: Workflow-defined permissions are automatically
"clamped" by repository or organization-level maximum settings.
Workflows cannot escalate their own permissions beyond these limits.

### 2. Organization & Repository Settings

- **Settings UI**: Added new settings pages at both Organization and
Repository levels to manage Actions token defaults and maximums.
- **Inheritance**: Repositories can be configured to "Follow
organization-level configuration," simplifying management across large
organizations.
- **Cross-Repository Access**: Added a policy to control whether Actions
workflows can access other repositories or packages within the same
organization. This can be set to "None," "All," or restricted to a
"Selected" list of repositories.

### 3. Security Hardening

- **Fork Pull Request Protection**: Tokens for workflows triggered by
pull requests from forks are strictly enforced as read-only, regardless
of repository settings.
- ~~**Package Access**: Actions tokens can now only access packages
explicitly linked to a repository, with cross-repo access governed by
the organization's security policy.~~ **EDIT removed
https://github.com/go-gitea/gitea/pull/36173#issuecomment-3873675346**
- **Git Hook Integration**: Propagates Actions Task IDs to git hooks to
ensure that pushes performed by Actions tokens respect the specific
permissions granted at runtime.

### 4. Technical Implementation

- **Permission Persistence**: Parsed permissions are calculated at job
creation and stored in the `action_run_job` table. This ensures the
token's authority is deterministic throughout the job's lifecycle.
- **Parsing Priority**: Implemented a priority system in the YAML parser
where the broad `contents` scope is applied first, allowing granular
scopes like `code` or `releases` to override it for precise control.
- **Re-runs**: Permissions are re-evaluated during a job re-run to
incorporate any changes made to repository settings in the interim.

### How to Test

1. **Unit Tests**: Run `go test ./services/actions/...` and `go test
./models/repo/...` to verify parsing logic and permission clamping.
2. **Integration Tests**: Comprehensive tests have been added to
`tests/integration/actions_job_token_test.go` covering:
   - Permissive vs. Restricted mode behavior.
   - YAML `permissions:` keyword evaluation.
   - Organization cross-repo access policies.
- Resource access (Git, API, and Packages) under various permission
configs.
3. **Manual Verification**: 
   - Navigate to **Site/Org/Repo Settings -> Actions -> General**.
- Change "Default Token Permissions" and verify that newly triggered
workflows reflect these changes in their `GITEA_TOKEN` capabilities.
- Attempt a cross-repo API call from an Action and verify the Org policy
is enforced.

2a828e2798 Clarify path param naming (#32969)
In history (from some legacy frameworks), both `:name` and `name` are
supported as path path name, `:name` is an alias to `name`.

To make code consistent, now we should only use `name` but not `:name`.

Also added panic check in related functions to make sure the name won't
be abused in case some downstreams still use them.
