How to fix?

Upgrade sulu/sulu to version 2.5.10 or higher.

Overview

sulu/sulu is a highly extensible open-source PHP content management system based on the Symfony framework.

Affected versions of this package are vulnerable to Information Exposure. This issue allows the Admin Login form to detect which user (username, email) exists and which ones do not exist.

Note:

Sulu Installation not using the old Symfony 5.4 security System and previous version are not impacted by this Security issue.

Workaround

Users who are unable to upgrade to the fixed version can create a custom AuthenticationFailureHandler which does not return the $exception->getMessage(); instead the $exception->getMessageKey();.
