CVE-2026-104632

Description

Gitea Actions blocks the jobs of workflow runs from first-time fork pull request contributors until a maintainer approves the run. The rerun path only required a run to be finished and built the new attempt's jobs without considering the pending approval, so when a user with Actions write access cancelled a run that was awaiting approval and then re-ran it, the new jobs were created as waiting rather than blocked while the run still recorded that approval was required. Cancelling and re-running stale fork checks is a routine action that does not involve the approval control, so where Actions is enabled and a matching runner is registered, workflow code taken from the fork pull request head could run on the repository's runners without an explicit approval.
