DescriptionThe Static Block plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.2. This is due to the static_block_content() shortcode handler retrieving a post via get_post() using an attacker-supplied 'id' attribute and outputting its post_content without verifying the post's status (private, draft, pending) or the requesting user's capability to view it. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of arbitrary posts, including private and draft static blocks (and any other post type) created by administrators, by embedding the [static_block_content id="X"] shortcode in their own content and previewing it.
