## Overview

Admidio versions before 5.0.11 contain a reflected cross-site scripting vulnerability in the SSO/SAML endpoint that echoes unencoded exception messages to the HTTP response. Unauthenticated attackers can inject arbitrary JavaScript through SAML Issuer elements or LightSaml library parameters to execute code in users' browsers and hijack sessions.
