CVE-2026-104626 is a high-severity flaw (CVSS 8.8) affecting gitea. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A user who can open a fork pull request can place workflow content with a shared run-level concurrency group into a Gitea Actions run that is awaiting approval. When a later run in that group cancels the blocked job, the run becomes terminal while still marked as needing approval. If a maintainer later approves the run, Gitea passed the already-cancelled job back through concurrency preparation, set it to waiting, and made it claimable by a match
