AI-suggested

Upgrade Gitea to version 28.4.0 or later, where the token endpoint properly enforces user sign-in status and invalidates tokens for deactivated or prohibited accounts. No other mitigation is required as the fix addresses the root cause.

Description

Gitea versions prior to 28.4.0 have an insufficient session expiration vulnerability when acting as an OAuth2 or OpenID Connect provider. The token endpoint did not verify the user's sign-in status, allowing refresh tokens and unused authorization codes to be exchanged for new tokens even after account deactivation or sign-in prohibition. This could allow continued access for users who should no longer be signed in. The issue is fixed in version 28.4.0, where the token endpoint refuses users who may not sign in and token introspection marks their tokens as inactive.
