What fixes it

  • 1.27.0code.gitea.io/gitea, goGitHubgo get code.gitea.io/gitea@v1.27.0

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
