CVE-2026-25946 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in Gitea versions through 1.25.4, when OpenID sign-in is enabled. This vulnerability allows unauthenticated remote attackers to send requests to internal loopback or private-network HTTP services, potentially exposing sensitive internal service behavior and enabling interaction with otherwise unreachable resources.
Users are advised to update Gitea to version 1.27.0 or later, where this vulnerability has been patched.
