{"id":"CVE-2026-73535","published":"2026-10-14T15:17:23.517","lastModified":"2026-10-14T16:04:39.483","description":"Gitea's OpenID connect handler accepts a user's password without enforcing enrolled TOTP or WebAuthn verification before completing sign-in and linking an OpenID identifier. When OpenID sign-in is enabled, an attacker who knows the victim's password can obtain a session and link an attacker-controlled identifier. The attacker can then sign in through that identifier without the victim's password or second factor, and a password change does not remove the link.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-304","CWE-696"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.2/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38805","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38810","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/38805","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38810","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","tags":[]}],"hasPoc":true,"ai":null}
