Detailsinfo

A vulnerability was found in Gitea up to 28.3.x and classified as critical. Affected by this issue is some unknown functionality of the component Token Endpoint. The manipulation with an unknown input leads to a improper authorization vulnerability. Using CWE to declare the problem leads to CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Impacted is confidentiality, integrity, and availability. CVE summarizes:

When Gitea acts as an OAuth2 or OpenID Connect provider, the token endpoint did not check the state of the user. After an administrator deactivated an account or prohibited its sign-in, existing refresh tokens and unused authorization codes of that user could still be exchanged for new tokens, so applications that sign users in through Gitea kept them signed in. The token endpoint now refuses users who may not sign in, and token introspection reports their tokens as inactive.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-128359 since 11/15/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1548.002 by the MITRE ATT&CK project.
