{"id":"CVE-2026-45048","aliases":["GHSA-vvhj-w2jq-263q"],"url":"https://o3.security/vulnerability/CVE-2026-45048","summary":"OpenAM Authenticated Privilege Escalation via Raw Token Disclosure Session RPC","details":"Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, SessionRequestHandler in the session management endpoint does not enforce ownership or privilege checks when a low-privileged authenticated user queries session information in deployments using stateful session storage. A requester who knows a target identity identifier can retrieve another user's active session credentials, including credentials for a more privileged account, and use them to hijack that session. This issue is fixed in version 16.1.1.","published":"2026-09-15T09:48:50.335Z","modified":"2026-09-19T08:14:24.419675Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.0025,"percentile":0.16572,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-core","fixedVersion":"16.1.1"}],"fix":{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/f775b42236b3cb94e3a02a19f4a4f4f5cc0b91c4","label":"OpenIdentityPlatform/OpenAM@f775b42"},"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/2026/45xxx/CVE-2026-45048.json"},{"type":"ADVISORY","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-vvhj-w2jq-263q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45048"},{"type":"FIX","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/f775b42236b3cb94e3a02a19f4a4f4f5cc0b91c4"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T08:14:24.419675Z"}}
