CVE-2026-6703

Responsive Blocks <= 2.2.1 - Missing Authorization to Authenticated (Contributor+) Arbitrary Modification via AJAX Actions

Responsive Blocks <= 2.2.1 - Missing Authorization to Authenticated (Contributor+) Arbitrary Modification via AJAX Actions

The Responsive Blocks – Page Builder for Blocks & Patterns plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 2.2.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to modify global site-wide plugin configuration options, including toggling custom CSS, disabling blocks, changing layout defaults such as content width, container padding, and container gap, and altering auto-block-recovery behavior.
