Static Block, CVE-2026-10780

CVE, Research URL: CVE-2026-10780
Home page URL: Security reports for Static Block
Application: Static Block
Published on: Jun 16, 2026
Research Description: 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.
Affected versions: max 2.2.
Status: vulnerable
