Attackers holding a trusted-CA-chained certificate can make OpenAM request internal hosts, capture configured CRL update credentials, overwrite stored revocation data to block certificate authentication for that CA, and tie up authentication threads.","epss":{"date":"2026-11-10","percentile":0.05404,"score":0.00162},"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},{"score":6.3,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":6.5,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"}],"modifiedAt":1794488169609,"publishedAt":1794101875523,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-g5vw-v384-gw9v"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/openam-before-16.1.4-ssrf-and-crl-tampering-via-certificate-crl-distribution-point"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-g5vw-v384-gw9v"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/openam-before-16.1.4-ssrf-and-crl-tampering-via-certificate-crl-distribution-point"}],"remediation":[],"revision":"350d58a4a2ff16cb05a08ac5803b34603caeb3d6043d8d586bb8c3d891508d79","sources":[{"modifiedAt":1794488169609,"name":"CNA: VulnCheck","retrievedAt":1794488931126,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123552"},{"modifiedAt":1794348809767,"name":"NVD","retrievedAt":1794356340190,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123552"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794377572628,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-123552"}],"ssvc":{"assessedAt":1794488148528,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"OpenAM before 16.1.4 SSRF and CRL Tampering via Certificate CRL Distribution Point","updatedAt":1794488931126}
