 "title": "PublishPress Permissions: Access Control, Content Permissions, User Access <= 4.9.1 - Authenticated (Subscriber+) Privilege Escalation via Revision Capability Grant",
 "description": "The PublishPress Permissions plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9.1, due to the Collaboration module's limited-revisor handling adding the 'edit_posts' capability (and the post type's edit_posts capability) to the current user on any admin request that references a draft revision the user authored, instead of only on the revision edit screen. This makes it possible for authenticated attackers with subscriber-level access who have been allowed to create revisions to hold the general 'edit_posts' capability for any admin or admin-ajax request they make, and perform actions limited to that capability. This requires PublishPress Revisions to be active.",
