Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The auto-merge workflow historically trusted the 'github.actor' context during 'workflow_run' events, which could allow malicious external actors to trigger unauthorized privileged actions on the repository.
Credential Leak: Default behavior in checkout actions allowed credentials to persist in the workspace, exposing the ambient GitHub token to potential theft by subsequent steps or untrusted dependencies run during the build.
