The goto parameter of the /preLogin endpoint is stored as the RelayState of the Liberty ID-FF authentication request without validation, and after the user completes single sign-on at the identity provider, the assertion consumer service redirects the browser to that value. A remote unauthenticated attacker can induce a user to access a crafted URL and, after the user authenticates, redirect the user to an arbitrary website, which may be used for phishing. Only deployments in which a Liberty ID-FF hosted service provider is configured are affected; Liberty ID-FF is not configured by default. This issue is fixed in 14.0.6, which disables the legacy Liberty ID-FF endpoints.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.1,"severity":"medium","source":"CNA: openam-jp","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},{"score":6.1,"severity":"medium","source":"CNA: openam-jp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794193111602,"publishedAt":1794193111602,"references":[{"source":"CNA: openam-jp","tags":["vendor-advisory"],"url":"https://openam-jp.github.io/Advisories/CVE-2026-121825/"},{"source":"CNA: openam-jp","tags":["related"],"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-5c3q-hp86-xjr8"}],"remediation":[{"kind":"fix","source":"CNA: openam-jp","text":"Upgrade to OpenAM (OpenAM Consortium Edition) 14.0.6 or later.
