The advisory
The AI Engine WordPress plugin before 3.7.9 does not check that the item passed to one of its media actions belongs to the requesting user before converting it to an attachment and permanently deleting it, allowing users with the Editor role and above to delete arbitrary posts of any type, including content they cannot otherwise delete such as navigation menus, block templates and global styles.
