Themify Builder, CVE-2026-75027

CVE, Research URL: CVE-2026-75027
Home page URL: Security reports for Themify Builder
Application: Themify Builder
Published on: Aug 22, 2026
Research Description: The Themify Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.8.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to modify the stored Themify Builder styling data (padding and margin properties) of arbitrary posts, including private and draft posts, by supplying an attacker-controlled post ID and JSON styling payload. The nonce required by the handler is automatically emitted to all frontend pages rendered by the builder via wp_localize_script, meaning any unauthenticated visitor can trivially retrieve a valid nonce from page source and satisfy the only access control in place.
Affected versions: max 7.8.1.
Status: vulnerable
