In in wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php in
WordPress 3.7 to 5.3.0, authenticated users who do not have the rights to
publish a post are able to mark posts as sticky or unsticky via the REST
API. For example, the contributor role does not have such rights, but this
allowed them to bypass that. This has been patched in WordPress 5.3.1,
along with all the previous WordPress versions from 3.7 to 5.3 via a minor
release.
