Description
Coder before 2.23.0 contains a session expiration bypass vulnerability that allows authenticated users to retain access after OIDC token expiry when no refresh token is issued. Users can keep their APIKey cookie active through regular use, extending it every 24 hours to access Coder indefinitely after losing OIDC authorization.
