| # PROCESS | |
| # | |
| # 1. Fetch PR details previously saved from untrusted location | |
| # 2. Parse details for safety | |
| # 3. Confirm there is a related issue for newly opened PR | |
| # 4. Verify if PR template is used and legal acknowledgement hasn't been removed | |
| # USAGE | |
| # | |
| # NOTE: meant to be used with ./.github/workflows/record_pr.yml | |
| # | |
| # Security Note: | |
| # | |
| # This workflow depends on "Record PR" workflow that runs in an untrusted location (forks) instead of `pull_request_target`. | |
| # This enforces zero trust where "Record PR" workflow always runs on fork with zero permissions on GH_TOKEN. | |
| # When "Record PR" completes, this workflow runs in our repository with the appropriate permissions and sanitize inputs. | |
| # | |
| # Coupled with "Approve GitHub Action to run on forks", we have confidence no privilege can be escalated, | |
| # since any malicious change would need to be approved, and upon social engineering, it'll have zero permissions. | |
