{"id":"CVE-2026-45049","published":"2026-10-29T22:17:02.400","lastModified":"2026-10-29T22:17:02.400","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.","cvssScore":8.3,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","cwes":["CWE-201"],"vendors":[],"products":[],"references":[{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/bda647f8540d8fb28aaaed716914692678c5a0a7","tags":[]},{"url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1","tags":[]},{"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-r9pv-5rpp-vm8g","tags":[]}],"exploitRefs":[{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/bda647f8540d8fb28aaaed716914692678c5a0a7","tags":[]},{"url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1","tags":[]},{"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-r9pv-5rpp-vm8g","tags":[]}],"hasPoc":true,"ai":null}
