CVE-2026-10780
Received Received - Intake
Insecure Direct Object Reference in Static Block WordPress Plugin

Publication date: 2026-06-16

Last updated on: 2026-06-16

Assigner: Wordfence

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.

Executive Summary

The Static Block plugin for WordPress has a vulnerability called Insecure Direct Object Reference (IDOR) in all versions up to and including 2.2.

This happens because the shortcode handler static_block_content() retrieves a post using an attacker-supplied 'id' attribute without verifying the post's status (such as private, draft, or pending) or whether the user has permission to view it.

As a result, authenticated users with contributor-level access or higher can read the contents of arbitrary posts, including private and draft static blocks or other post types created by administrators, by embedding the shortcode [static_block_content id="X"] in their own content and previewing it.

Impact Analysis

This vulnerability allows attackers with contributor-level access or above to read private or draft content that they should not normally be able to access.

This could lead to unauthorized disclosure of sensitive or confidential information contained in private posts or static blocks created by administrators.

Since the vulnerability does not allow modification or deletion, the impact is limited to confidentiality loss.
