0085208689 fix: require explicit acknowledgment for wildcard write permission bypass
SECURITY FIX: Addresses authorization_bypass vulnerability (LOW severity)

The allowed_non_write_users='*' configuration previously bypassed write
permission checks for all users with only a warning. This created a
security misconfiguration risk.

Changes:
- Added new input 'bypass_write_permission_check_acknowledgment' required
  when using wildcard (*)
- Modified checkWritePermissions() to throw error if wildcard used without
  explicit acknowledgment flag
- Updated all documentation (security.md, usage.md) with new requirement
- Updated example workflows to include acknowledgment flag
- Added tests for new validation behavior

This prevents accidental security misconfigurations while maintaining the
feature for intentional use cases like issue triage workflows.

Affected file: src/github/validation/permissions.ts:27
Category: authorization_bypass
Severity: LOW

005436f51d fix: parse ALL --allowed-tools flags, not just the first one (#801)
The parseAllowedTools() function previously used .match() which only
returns the first match. This caused tools specified in subsequent
--allowed-tools flags to be ignored during MCP server initialization.

Changes:
- Add /g flag to regex patterns for global matching
- Use matchAll() to find all occurrences
- Deduplicate tools while preserving order
- Make unquoted pattern not match quoted values

Fixes #800

5da7ba548c feat: add path validation for commit_files MCP tool (#796)
Add validatePathWithinRepo helper to ensure file paths resolve within the repository root directory. This hardens the commit_files tool by validating paths before file operations.

Changes:
- Add src/mcp/path-validation.ts with async path validation using realpath
- Update commit_files to validate all paths before reading files
- Prevent symlink-based path escapes by resolving real paths
- Add comprehensive test coverage including symlink attack scenarios

* fix: use original title from webhook payload instead of fetched title

- Add extractOriginalTitle() helper to extract title from webhook payload
- Add originalTitle parameter to fetchGitHubData()
- Update tag mode to pass original title from webhook context
- Add tests for extractOriginalTitle and originalTitle parameter

This ensures the title used in prompts is the one that existed when the
trigger event occurred, rather than a potentially modified title fetched
later via GraphQL.

* fix: add title sanitization and explicit TOCTOU test

- Apply sanitizeContent() to titles in formatContext() for defense-in-depth
- Add explicit test documenting TOCTOU prevention for title handling

c9ec2b02b4 fix: set CLAUDE_CODE_ENTRYPOINT for SDK path to match CLI path (#791)
Previously, the SDK path would result in the CLI setting the entrypoint
to 'sdk-ts' internally, while the non-SDK (CLI) path would correctly
set it to 'claude-code-github-action' based on the CLAUDE_CODE_ACTION
env var.

This change explicitly sets CLAUDE_CODE_ENTRYPOINT in both:
1. The action.yml env block (for consistency)
2. The SDK options env (to override the CLI's internal default)

The CLI respects pre-set entrypoint values, so this ensures consistent
user agent reporting for both execution paths.

63ea7e3174 fix: prevent orphaned installer processes from blocking retries (#790)
* fix: prevent orphaned installer processes from blocking retries

When the `timeout` command expires during Claude Code installation, it only
kills the direct child bash process, not the grandchild installer processes.
These orphaned processes continue holding a lock file, causing retry attempts
to fail with "another process is currently installing Claude".

Add `--foreground` flag to run the command in a foreground process group so
all child processes are killed on timeout. Add `--kill-after=10` to send
SIGKILL if SIGTERM doesn't terminate processes within 10 seconds.

653f9cd7a3 feat: support local plugin marketplace paths (#761)
* feat: support local plugin marketplace paths

Enable installing plugins from local directories in addition to remote
Git URLs. This allows users to use local plugin marketplaces within their
repository without requiring them to be hosted in a separate Git repo.

Example usage:
  plugin_marketplaces: "./my-local-marketplace"
  plugins: "my-plugin@my-local-marketplace"

Supported path formats:
- Relative paths: ./plugins, ../shared-plugins
- Absolute Unix paths: /home/user/plugins
- Absolute Windows paths: C:\Users\user\plugins

Fixes #664

* feat: send user request as separate content block for slash command support

When in tag mode with the SDK path, extracts the user's request from the

7e4bf87b1c feat: add ssh_signing_key input for SSH commit signing (#784)
* feat: add ssh_signing_key input for SSH commit signing

Add a new ssh_signing_key input that allows passing an SSH signing key
for commit signing, as an alternative to the existing use_commit_signing
(which uses GitHub API-based commits).

When ssh_signing_key is provided:
- Git is configured to use SSH signing (gpg.format=ssh, commit.gpgsign=true)
- The key is written to ~/.ssh/claude_signing_key with 0600 permissions
- Git CLI commands are used (not MCP file ops)
- The key is cleaned up in a post step for security

Behavior matrix:
| ssh_signing_key | use_commit_signing | Result |
|-----------------|-------------------|--------|
| not set         | false             | Regular git, no signing |
| not set         | true              | GitHub API (MCP), verified commits |
| set             | false             | Git CLI with SSH signing |
| set             | true              | Git CLI with SSH signing (ssh_signing_key takes precedence)

* docs: add SSH signing key documentation

- Update security.md with detailed setup instructions for both signing options
- Explain that ssh_signing_key enables full git CLI operations (rebasing, etc.)
- Add ssh_signing_key to inputs table in usage.md
- Update bot_id/bot_name descriptions to note they're needed for verified commits

* fix: address security review feedback for SSH signing

- Write SSH key atomically with mode 0o600 (fixes TOCTOU race condition)
- Create .ssh directory with mode 0o700 (SSH best practices)
- Add input validation for SSH key format
- Remove unused chmod import
- Add tests for validation logic

When Claude reviews PRs and identifies fixable issues, it now includes
inline links that open Claude Code with the fix request pre-loaded.

Format: [Fix this →](https://claude.ai/code?q=<URI_ENCODED_INSTRUCTIONS>&repo=<REPO>)

This enables one-click fix requests directly from code review comments.

* feat: add include_fix_links input to control Fix this links

Adds a configurable input to enable/disable the "Fix this →" links
in PR code reviews. Defaults to true for backwards compatibility.

95be46676d fix: set GH_TOKEN alongside GITHUB_TOKEN for gh CLI precedence (#752)
The gh CLI prefers GH_TOKEN over GITHUB_TOKEN. When a calling workflow
sets GH_TOKEN in env, the action's GITHUB_TOKEN was being ignored,
causing the gh CLI to use the wrong token (e.g., the default workflow
token instead of an App token).

This ensures Claude's gh CLI commands use the action's prepared token.

f98c1a5aa8 fix: respect user's --setting-sources in claude_args (#750)
When users specify --setting-sources in claude_args (e.g., '--setting-sources user'),
the action now respects that value instead of overriding it with all three sources.

This fixes an issue where users who wanted to avoid in-repo configs would still
have them loaded because the settingSources was hardcoded to ['user', 'project', 'local'].

d7b6d50442 fix: merge multiple --mcp-config flags and support --allowed-tools parsing (#748)
* fix: merge multiple --mcp-config flags instead of overwriting

When users provide their own --mcp-config in claude_args, the action's
built-in MCP servers (github_comment, github_ci, etc.) were being lost
because multiple --mcp-config flags were overwriting each other.

This fix:
- Adds mcp-config to ACCUMULATING_FLAGS to collect all values
- Changes delimiter to null character to avoid conflicts with JSON
- Adds mergeMcpConfigs() to combine mcpServers objects from multiple configs
- Merges inline JSON configs while preserving file path configs

* fix: support hyphenated --allowed-tools flag and multiple values

The --allowed-tools flag was not being parsed correctly when:
1. Using the hyphenated form (--allowed-tools) instead of camelCase (--allowedTools)
2. Passing multiple space-separated values after a single flag
   (e.g., --allowed-tools "Tool1" "Tool2" "Tool3")

This fix:
- Adds hyphenated variants (allowed-tools, disallowed-tools) to ACCUMULATING_FLAGS
- Updates parsing to consume all consecutive non-flag values for accumulating flags
- Merges values from both camelCase and hyphenated variants

## Commit Signing
Commits made by Claude through this action are no longer automatically signed with commit signatures. To enable commit signing set `use_commit_signing: True` in the workflow(s). This ensures the authenticity and integrity of commits, providing a verifiable trail of changes made by the action.
By default, commits made by Claude are unsigned. You can enable commit signing using one of two methods:
### Option 1: GitHub API Commit Signing (use_commit_signing)
This uses GitHub's API to create commits, which automatically signs them as verified from the GitHub App:
```yaml
- uses: anthropics/claude-code-action@main
with:
use_commit_signing: true
```
This is the simplest option and requires no additional setup. However, because it uses the GitHub API instead of git CLI, it cannot perform complex git operations like rebasing, cherry-picking, or interactive history manipulation.
### Option 2: SSH Signing Key (ssh_signing_key)
This uses an SSH key to sign commits via git CLI. Use this option when you need both signed commits AND standard git operations (rebasing, cherry-picking, etc.):
```yaml
- uses: anthropics/claude-code-action@main
with:
ssh_signing_key: ${{ secrets.SSH_SIGNING_KEY }}
bot_id: "YOUR_GITHUB_USER_ID"
bot_name: "YOUR_GITHUB_USERNAME"
```
Commits will show as verified and attributed to the GitHub account that owns the signing key.
**Setup steps:**
1. Generate an SSH key pair for signing:
```bash
ssh-keygen -t ed25519 -f ~/.ssh/signing_key -N "" -C "commit signing key"
```
2. Add the **public key** to your GitHub account:
- Go to GitHub → Settings → SSH and GPG keys
- Click "New SSH key"
- Select **Key type: Signing Key** (important)
- Paste the contents of `~/.ssh/signing_key.pub`
3. Add the **private key** to your repository secrets:
- Go to your repo → Settings → Secrets and variables → Actions
- Create a new secret named `SSH_SIGNING_KEY`
- Paste the contents of `~/.ssh/signing_key`
4. Get your GitHub user ID:
```bash
gh api users/YOUR_USERNAME --jq '.id'
```
5. Update your workflow with `bot_id` and `bot_name` matching the account where you added the signing key.
**Note:** If both `ssh_signing_key` and `use_commit_signing` are provided, `ssh_signing_key` takes precedence.
