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.\n\n## Affected\n\n- `gitea < 28.0.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `gitea 28.0.0`","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":217739,"id":"CVE-2026-104632","ts":1791406427414,"field":"cvss","old":null,"new":"8.8"},{"seq":217738,"id":"CVE-2026-104632","ts":1791406427414,"field":"severity","old":"none","new":"high"}]}
