Official description

A remote code execution vulnerability in ZoneMinder 1.39.17 allows any authenticated user to execute OS commands by exploiting a broken permission check in the Filter class. The canEdit() and canDelete() methods invoke nonexistent methods on the ZM\User class, causing PHP __call() to return a truthy value that bypasses the permission check for all users.
