{"schema":"threatline.record/2","record":{"id":"CVE-2026-73535","aliases":["GHSA-8xjr-x7rg-hp5h"],"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.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-73535","source_modified_at":"2026-10-18T13:32:08.609Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Gitea","vendor":"Gitea","versions":[{"lessThanOrEqual":"1.27.1","status":"affected","version":"0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","source_modified_at":"2026-08-14T16:34:46Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"go","name":"gitea.dev"},"range":"<= 1.27.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","source_modified_at":"2026-08-14T16:34:46Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"go","name":"gitea.dev"},"version":"1.27.2"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00447,"percentile":0.37873,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:37:39.073Z","modified_at":"2026-10-18T13:32:08.609Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-73535","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T13:32:08.609Z"},{"source":"GitHub Advisory Database","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","fetched_at":"2026-10-23T18:58:35.272684Z","source_modified_at":"2026-08-14T16:34:46Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-73535","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8xjr-x7rg-hp5h","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-1.27.2/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/38805","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/38810","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-18T13:31:49.410645Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T13:32:08.609Z","content_hash":"9e9105a2b442a3621a81b79843a370f03ae2a40cd422a90ff42ecae760aebde8"}}
