{"id":"CVE-2026-45049","state":"PUBLISHED","title":"OpenAM Session Hijacking via CDSSO","description":"Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the `Cross-Domain Single Sign-On` (`CDSSO`) servlet allows a logged-in user's raw OpenAM session token to be POSTed to an attacker-controlled URL. An attacker who induces an authenticated victim to visit a crafted URL can receive the session credential and potentially hijack the session. Deployments must have `CDSSO` enabled, as is common in multi-domain deployments, and exploitation is additionally gated on a non-default configuration being absent. This issue is fixed in version 16.1.1.","publishedAt":"2026-10-29T21:13:55.740Z","updatedAt":"2026-10-29T21:13:55.740Z","severity":{"score":8.3,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["OpenIdentityPlatform OpenAM"],"affected":[{"vendor":"OpenIdentityPlatform","product":"OpenAM","versions":[{"version":"< 16.1.1","status":"affected"}]}],"references":["https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-r9pv-5rpp-vm8g","https://github.com/OpenIdentityPlatform/OpenAM/commit/bda647f8540d8fb28aaaed716914692678c5a0a7","https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1"],"weaknesses":["CWE-201"],"ingestedAt":"2026-10-29T23:14:04.755Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/45xxx/CVE-2026-45049.json","commit":"dc7676b3f67d6707e4927968546e7e0125ff7ec7","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-45049","state":"PUBLISHED","datePublished":"2026-10-29T21:13:55.740Z","dateUpdated":"2026-10-29T21:13:55.740Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-08T18:07:27.341Z"},"containers":{"cna":{"title":"OpenAM Session Hijacking via CDSSO","descriptions":[{"lang":"en","value":"Open Access Management (OpenAM) is an access management solution.
