Every CVE for Gitea

Exploited in the last 30 days

When OpenID sign-in is enabled, Gitea accepts a user-supplied OpenID URL and performs discovery requests without validating the destination against internal network addresses. An unauthenticated remote attacker can cause the server to contact loopback or private-network HTTP services. This can expose internal service behavior and enable interaction with resources that are not directly reachable by the attacker.
