Description
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'postId' parameter of the b2s_ship_item and b2s_ship_item_reload_url AJAX actions in all versions up to, and including, 9.1.4, due to missing validation on a user-controlled key. The getShipItem() and getShipItemReloadUrl() functions check only the edit_posts capability and a nonce, and never check whether the current user may read the referenced post. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve the title, content excerpts and permalinks of private, draft or pending posts belonging to other users.
