Upgrade admidio/admidio to version 5.0.9 or higher.
Overview
admidio/admidio is a free open source user management system for websites of organizations and groups.
Affected versions of this package are vulnerable to Improper Authentication in the handleIntrospectionRequest and handleRevocationRequest functions. An attacker can gain unauthorized access to connected resource servers by submitting arbitrary or fabricated tokens, as the endpoints always return successful responses without validating the token or authenticating the calling resource server. This allows impersonation of any user and prevents revocation of compromised tokens.
