Static Block <= 2.2 - Insecure Direct Object Reference to Authenticated (Contributor+) Sensitive Information Disclosure via Shortcode 'id' Attribute
The 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.
