Description

Currently, the check-pr-title job has a security vulnerability. If you give the PR a bad title, the job can run arbitrary code.

Changes

  • Fix prompt injection by pulling the PR title as an environment variable.
  • Also, restricted the job to only pull_request trigger.

Design Decisions

  • It is better to pull out this job into a separate workflow with a unique trigger, but I chose not to because it is currently only one job.

Checklist

  • Tests pass
  • Docs updated
