{"id":"CVE-2026-45049","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-45049","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.","published":"2026-06-23T17:33:14Z","modified":"2026-06-23T17:56:30.931922Z","cvss":{"score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-federation","fixedVersion":"16.1.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-r9pv-5rpp-vm8g"},{"type":"PACKAGE","url":"https://github.com/OpenIdentityPlatform/OpenAM"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-06-23T17:56:30.931922Z"}}
