Description

The Document Engine plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.3 via the 'pdf_id' attribute of the PDF viewer block. The plugin does not check that the referenced attachment is public or readable by the current user. This makes it possible for authenticated attackers with Contributor-level access and above to reveal the file URLs of media attached to private or draft posts, by referencing the attachment IDs in a block and previewing their own post.
