Prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path.

This issue is fixed in version 16.1.1.","published":"2026-09-15T09:42:18.153Z","modified":"2026-09-17T08:08:36.748947Z","cvss":null,"epss":{"score":0.00448,"percentile":0.38171,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-federation-library","fixedVersion":"16.1.1"}],"fix":{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/2f5e9bf4c28a4c9e97ded6ebd75e4e1ec241c894","label":"OpenIdentityPlatform/OpenAM@2f5e9bf"},"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44793.json"},{"type":"ADVISORY","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-fhrq-3gmx-p879"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44793"},{"type":"FIX","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/2f5e9bf4c28a4c9e97ded6ebd75e4e1ec241c894"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T08:08:36.748947Z"}}
