CVE-2026-44793
OpenAM SAML2 Cluster Cookie-Hash-Redirect Path has Pre-authentication Reflected XSS via `FSUtils.postToTarget`
Impact
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.
