{"id":"CVE-2026-44793","summary":"OpenAM: Pre-authentication Reflected XSS in SAML2 Cluster Cookie-Hash-Redirect Path via `FSUtils.postToTarget`","details":"Open Access Management (OpenAM) is an access management solution. 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. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.","aliases":["GHSA-fhrq-3gmx-p879"],"modified":"2026-09-16T03:46:02.227788245Z","published":"2026-09-15T09:42:18.153Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44793.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44793.json"},{"type":"FIX","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/2f5e9bf4c28a4c9e97ded6ebd75e4e1ec241c894"},{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openidentityplatform/openam","events":[{"introduced":"0"},{"fixed":"fe2271ec119e827b4252cec20293480322a84789"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"16.1.1"}],"source":"AFFECTED_FIELD"}}],"versions":["16.0.6","16.0.5","16.0.4","16.0.3","15.2.2","15.2.1","15.2.0","15.1.6","15.1.5","15.1.4","15.1.3","15.1.2","15.1.1","15.1.0","15.0.4","15.0.3","15.0.2","15.0.1","15.0.0","14.8.4","14.8.3","14.8.2","14.8.1","14.7.4","14.7.3","14.7.2","14.7.1","14.7.0","14.6.6","14.6.5","14.6.4","14.6.3","14.6.2","14.5.4","14.5.3","14.5.2","14.5.1","14.4.2","14.4.1","14.3.1","14.2.2","14.2.1","14.1.17","14.1.16","14.1.13","14.1.12","14.1.11","14.1.10","14.1.9","14.1.8","14.1.7","14.1.6","14.1.5","14.1.4","14.1.3","14.1.2","14.1.1","14.0.6","14.0.5","14.0.4","14.0.3","14.0.2","14.0.1","14.0.0","13.0.0","13.0.0-RC10","13.0.0-RC9","13.0.0-RC8","13.0.0-RC7","13.0.0-RC6","13.0.0-RC5","13.0.0-RC4","13.0.0-RC3","13.0.0-RC2","13.0.0-RC1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44793.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:H/VA:N/SC:L/SI:H/SA:N"}]}
