CVE-2026-25946— Gitea OpenID discovery server-side request forgery

Quick assessment

Affected
Gitea Gitea
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

当启用 OpenID 登录时，Gitea 接受用户提供的 OpenID URL，并执行发现请求，但未对这些请求的目标地址是否属于内部网络地址进行验证。未经身份验证的远程攻击者可以促使服务器向回环地址或私有网络内的 HTTP 服务发起连接。这可能暴露内部服务的行为，并使得攻击者能够与那些通常无法直接访问的资源进行交互。

Vulnerability Title
Gitea OpenID discovery server-side request forgery
Source: CVE Program / CVE List V5
Vulnerability 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.
