Persistent account access via unrevoked login token
Published Aug 13, 2026 · Updated Aug 13, 2026
Insufficient session expiration in Gitea before 1.27.0 allows remote attackers with a stolen persistent-login token to retain account access. CheckAuthToken returns ErrAuthTokenInvalidHash on a rotated token hash mismatch, while autoSignIn clears only the victim's cookie and leaves the compromised database token valid. Exploitation requires prior theft and use of the cookie; the remote attacker retains the victim's account privileges after the victim reuses the stale token.
