Admidio before 5.0.11 contains an authentication bypass vulnerability in the forum module when configured in login-only mode. The access control logic in modules/forum.php fails to validate the login-only configuration state, allowing unauthenticated attackers to read forum topics and posts by directly accessing the module with read-only parameters.
