CVE-2026-6703

CVSS v3.1

4.3

Medium

AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
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.
