{"id":"GHSA-3w4h-g9f5-j84p","summary":"Casdoor  does not validate the AudienceRestriction element in SAML assertions","details":"In Casdoor versions 2.362.0 and earlier, the SAML service provider implementation does not validate the AudienceRestriction element in SAML assertions. The buildSp function in object/saml_sp.go never sets AudienceURI on the gosaml2 SAMLServiceProvider struct and never inspects WarningInfo.NotInAudience. This allows assertions issued for other service providers to be accepted by Casdoor.","aliases":["CVE-2026-9093","GO-2026-5894"],"modified":"2026-07-07T16:11:05.640243857Z","published":"2026-05-28T18:30:32Z","database_specific":{"cwe_ids":[],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-07-02T18:37:12Z","nvd_published_at":"2026-05-28T17:16:34Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-9093"},{"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-3w4h-g9f5-j84p/GHSA-3w4h-g9f5-j84p.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:H/I:H/A:H"}]}
