Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Packagist package thorsten/phpmyfaq is affected in versions before 4.2.0-alpha, and 4.2.0-alpha fixes it. An attacker needs a valid authenticated user account, since the chat user search endpoint does not escape the SQL LIKE wildcard characters % and _, which lets a search bypass the intended display-name filter. This allows any logged-in user to list active user IDs and display names; the advisory says to upgrade to 4.2.0-alpha or later.
