 "title": "PublishPress Permissions: Access Control, Content Permissions, User Access <= 4.9.1 - Authenticated (Contributor+) Missing Authorization to Enable Permissions Filtering for Post Types and Taxonomies",
 "description": "The PublishPress Permissions plugin for WordPress is vulnerable to unauthorized settings modification in all versions up to, and including, 4.9.1 due to a missing capability check and missing nonce validation on the 'pp_enable_post_type' parameter processed during post and term saves. This makes it possible for authenticated attackers with contributor-level access and above, who can save a post or term, to enable permissions filtering for a post type or taxonomy, changing the site's permissions configuration.",
