For a `pull_request_target` (PRT) run, Gitea loads the top-level workflow from the trusted base branch, but any local reusable workflow it calls (`uses: ./...`) was read from the PR **head** commit, which the fork author controls. ## Fix **Record the source commit where the content is read.** `DetectedWorkflow` now carries a `SourceCommitSHA` filled in next to `Content`, so the PRT detection pass at the base commit records the base SHA automatically. **Defense in depth.** `loadReusableWorkflowSource` pins the PR base commit for a PRT run's local `uses: ./...` rather than trusting the stored SHA. This also covers runs recorded before this change, whose rows still hold the head SHA and would otherwise resolve from the fork on rerun. Existing run rows are not migrated. --------- Co-authored-by: Zettat <zettat123@gmail.com>
