CVE-2026-121825 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 5.1 (medium) and affects OpenAM (OpenAM Consortium Edition); fixed in 14.0.6.

## Summary

OpenAM Consortium Edition contains an open redirect flaw in its Liberty ID-FF service provider single sign-on flow, and a remote attacker can reach it without logging in. An attacker can lure a user to a crafted URL so that, after the user authenticates, the browser is redirected to an arbitrary website, which may be used for phishing; this affects only deployments with a Liberty ID-FF hosted service provider configured, which is not the default setup.

## Affected

- OpenAM consortium OpenAM (OpenAM Consortium Edition): from 14.0.0, fixed in 14.0.6

## Description

OpenAM (OpenAM Consortium Edition) 14.0.5 and earlier contains an open redirect vulnerability (CWE-601) in the Liberty ID-FF service provider single sign-on flow. 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.
