CVE-2026-119545 · Severity: medium · CVSS 5.3 · Published 2026-10-30

Forgejo is a self-hosted Git forge platform that allows organizations to manage code repositories. When OpenID sign-in is enabled, unauthenticated attackers can trigger the server to make HTTP requests to arbitrary internal addresses, including loopback interfaces and cloud metadata endpoints. This enables port scanning, network reconnaissance, and potential data disclosure from internal services.

## Technical details

The vulnerability is a server-side request forgery (SSRF) in the OpenID discovery handler at POST /user/login/openid. Unauthenticated attackers submit OpenID identifier URLs that are passed unsanitized to the yohcop openid-go library, which performs Yadis and HTML discovery requests using http.DefaultClient with no IP filtering or host validation. Unlike webhooks and migrations which apply network policies, the OpenID path bypasses these protections, allowing blind SSRF to loopback, RFC1918, and link-local addresses.
