Summary

Renovate before 44.61.3 has a protection mechanism failure (CWE-693) that skips minimumReleaseAge checks when a user requests a PR rebase with the rebase/retry checkbox. A remote attacker with no privileges who publishes a malicious dependency version can get it pushed into the PR and run in CI before the required release age elapses, but a user must trigger the rebase. Mend products renovate-ce, renovate-ee-server and renovate-ee-worker before 15.5.0, and the Mend Renovate helm charts before 15.5.0 and before 10.5.0, are also affected.
