{"id":"GHSA-gv4m-v8c8-hr3g","summary":"Casdoor allows users to bypass configured MFA requirements","details":"Casdoor versions 2.362.0 and earlier contain a logic flaw in the social‑login binding flow that allows users to bypass configured MFA requirements. The binding‑rule code path in controllers/auth.go calls HandleLoggedIn directly without invoking checkMfaEnable. Any user authenticating via this path is logged in without MFA enforcement.","aliases":["CVE-2026-9091","GO-2026-5896"],"modified":"2026-07-07T16:11:23.584657141Z","published":"2026-05-28T18:30:32Z","database_specific":{"github_reviewed_at":"2026-07-02T18:36:38Z","nvd_published_at":"2026-05-28T17:16:33Z","cwe_ids":["CWE-287"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-9091"},{"type":"PACKAGE","url":"https://github.com/casdoor/casdoor"},{"type":"WEB","url":"https://kb.cert.org/vuls/id/780781"}],"affected":[{"package":{"name":"github.com/casdoor/casdoor","ecosystem":"Go","purl":"pkg:golang/github.com/casdoor/casdoor"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"1.1000.1-0.20260321120606-239e8bd69487"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-gv4m-v8c8-hr3g/GHSA-gv4m-v8c8-hr3g.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
