Description
The Related Posts for WordPress plugin for WordPress is vulnerable to Sensitive Information Exposure via the Related Posts link screen and meta box in all versions up to, and including, 3.0.0, due to missing checks on whether the current user can read a post. The All Posts view of the link screen lists other users' private posts, with titles and dates. The link handlers (rp4wp_create_link and rp4wp_bulk) accept any post ID, and the Related Posts meta box shows the title of every linked post. This makes it possible for authenticated attackers with Contributor-level access and above to learn the titles of draft, pending, scheduled, private or trashed posts of other users by linking them to a post of their own.
