CVE-2026-44793 OpenIdentityPlatform CVE debrief
CVE-2026-44793 is a high-severity vulnerability in Open Access Management (OpenAM) that allows an unauthenticated attacker to execute script in the OpenAM origin by inducing a user to follow a crafted request. The issue is fixed in version 16.1.1. This vulnerability affects OpenAM deployments in non-default clustered configurations. Defenders should assess exposure and prioritize patching to prevent potential script execution. The vulnerability is caused by inconsistent encoding of user-supplied parameters in the SAML2 cluster cookie-hash redirect path.
