Overview

craftcms/cms is a content management system.

Affected versions of this package are vulnerable to Missing Authorization through the actionDeleteFolder process. An attacker can remove assets belonging to other users by exploiting insufficient permission checks during folder deletion operations. This is only exploitable if the attacker has been granted the deleteAssets permission but not the deletePeerAssets permission on a shared volume.
