WordPress Core 4.7.0 - 7.1.2 - Authenticated (Author+) Unauthorized Sticky Post Modification via REST API
WordPress Core is vulnerable to unauthorized sticky-post modification in versions 4.7 through 7.1.2 due to an incorrect capability condition in the REST posts controller. This makes it possible for authenticated attackers, with Author-level access and above, to make posts they can edit sticky and, in affected update paths, remove sticky status without possessing the edit_others_posts capability required for sticky-post management.
