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
* feat: skip permission check for GitHub App bot users
GitHub Apps (users ending with [bot]) now bypass permission checks
as they have their own authorization mechanism.

* feat: add allow_bot_users option to control bot user access
- Add allow_bot_users input parameter (default: false)
- Modify checkHumanActor to optionally allow bot users
- Add comprehensive tests for bot user handling
- Improve security by blocking bot users by default
This change prevents potential prompt injection attacks from bot users
while providing flexibility for trusted bot integrations.
