{"id":"CVE-2026-73535","summary":"Gitea second-factor bypass through OpenID identity linking","details":"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.","aliases":["GHSA-8xjr-x7rg-hp5h"],"modified":"2026-10-15T02:47:44.035923081Z","published":"2026-10-14T14:37:39.073Z","database_specific":{"cwe_ids":["CWE-304","CWE-696"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73535.json","cna_assigner":"Gitea"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.2/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73535.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38805"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38810"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73535"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"last_affected":"a62dfffbe7d3a454c2f2d3c4b2788ba432724a5f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.27.1"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.27.1","v1.27.0","v1.27.0-rc0","v1.28.0-dev","v1.27.0-dev","v1.26.0-dev","v1.25.0-dev","v1.24.0-dev","v1.22.0-rc1","v1.23.0-dev","v1.22.0-rc0","v1.21.0-rc0","v1.22.0-dev","v1.20.0-rc0","v1.21.0-dev","v1.20.0-dev","v1.19.0-rc0","v1.18.0-rc0","v1.19.0-dev","v1.18.0-dev","v1.17.0-dev","v1.16.0-rc1","v1.15.0-rc1","v1.16.0-dev","v1.15.0-dev","v1.14.0-dev","v1.13.0-dev","v1.12.0-dev","v1.10.5","v1.11.0-rc1","v1.10.0-rc1","v1.11.0-dev","v1.9.0-rc1","v1.10.0-dev","v1.9.0-dev","v1.7.0-dev","v1.6.0-rc1","v1.6.0-dev","v1.5.0-rc1","v1.5.0-dev","v1.1.0","v1.0.0","v0.9.99"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73535.json"}}],"schema_version":"1.9.0"}
