Gitea: OAuth2 sign-in reactivates an administrator-deactivated account on auth sources without refresh tokens (incomplete fix of #38009) (CVE-2026-55987)CVE-2026-55987 0 Gitea versions prior to 1.27.0 contain a vulnerability where OAuth2 sign-in reactivates user accounts that administrators have deactivated if the authentication source does not issue refresh tokens (e.g., GitHub or OIDC/OAuth2 without offline_access). This occurs because the system incorrectly uses an empty refresh token as a signal to reactivate accounts, which is the normal state for such sources. As a result, deactivated users can regain active status and full session access simply by signing in again, bypassing the administrator's deactivation. Accounts disabled with the stronger "Prohibit Login" setting are not affected. Join the discussion | GCVE Database | 07/21/2026, 21:02:10 UTC Added: 07/22/2026, 00:11:29 UTC |
