{"id":"GHSA-r9pv-5rpp-vm8g","summary":"OpenAM Unauthenticated Session Hijacking via Information Exposure in CDCServlet","details":"## Summary\n\n**Description**\n\nAn Information Exposure Through Sent Data (CWE-201) issue in OpenAM's 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. This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1.\n\nAn attacker who can induce a logged-in victim to visit a crafted URL may receive the victim's session credential, which could enable session hijacking.\n\n## Impact\nOpenAM deployments through version 16.0.6 that have CDSSO enabled are potentially affected. The CDSSO component is commonly enabled in multi-domain deployments. Exploitation requires user interaction — an authenticated user must be induced to visit an attacker-crafted URL — and is further gated on a non-default configuration being absent.\n\n## Patch\nThis has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.","aliases":["CVE-2026-45049"],"modified":"2026-06-23T17:56:30.931922Z","published":"2026-06-23T17:33:14Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-201"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-06-23T17:33:14Z"},"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-r9pv-5rpp-vm8g"},{"type":"PACKAGE","url":"https://github.com/OpenIdentityPlatform/OpenAM"}],"affected":[{"package":{"name":"org.openidentityplatform.openam:openam-federation","ecosystem":"Maven","purl":"pkg:maven/org.openidentityplatform.openam/openam-federation"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.1.1"}]}],"versions":["14.5.2","14.5.3","14.5.4","14.6.1","14.6.2","14.6.3","14.6.4","14.6.5","14.6.6","14.7.0","14.7.1","14.7.2","14.7.3","14.7.4","14.8.1","14.8.2","14.8.3","14.8.4","15.0.0","15.0.1","15.0.2","15.0.3","15.0.4","15.1.0","15.1.1","15.1.2","15.1.3","15.1.4","15.1.5","15.1.6","15.2.0","15.2.1","15.2.2","16.0.1","16.0.2","16.0.3","16.0.4","16.0.5","16.0.6","16.1.0"],"database_specific":{"last_known_affected_version_range":"\u003c= 16.0.6","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-r9pv-5rpp-vm8g/GHSA-r9pv-5rpp-vm8g.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
