DescriptionA broken access control vulnerability in Ghost Foundation Ghost 5.x allows authenticated Author-role users to delete posts owned by other users. The post model permissible() cascade is missing the branch that handles the combined isAuthor and isDestroy condition, causing the authorization check to fall through and permit the deletion. An attacker with an Author account can delete any post on the platform.
