The advisory
The Content Egg – Affiliate Product Importer & Price Comparison plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 12.0.0 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to create posts attributed to another user's account — typically an administrator — by supplying an admin-owned preset_id, causing wp_insert_post to record the administrator as post_author. This includes the ability to create published posts when the attacker already holds publish_posts capability for the preset's post type, resulting in administrator-attributed published content created by a lower-privileged user.
