Authorization Bypass in Themify Builder Plugin

Publication date: 2026-08-22

Last updated on: 2026-08-22

Assigner: Wordfence

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.

Executive Summary

The Themify Builder plugin for WordPress has an authorization bypass flaw in versions up to 7.8.0. This allows unauthenticated attackers to modify styling data (padding and margin) of any post, including private or draft posts, by providing a post ID and JSON payload. The plugin fails to properly verify user authorization for these actions.

Detection Guidance

Check WordPress sites using Themify Builder versions up to 7.8.0 for unauthorized style modifications in posts. Inspect frontend page sources for exposed nonces in wp_localize_script. Review server logs for suspicious POST requests targeting Themify Builder endpoints with JSON payloads.

Impact Analysis

Unauthenticated attackers could alter the appearance of your WordPress site's posts, including sensitive or unpublished content. This could lead to defacement, misleading styling changes, or potential manipulation of how content is displayed to visitors.

Compliance Impact

This vulnerability could potentially affect compliance with GDPR and HIPAA by allowing unauthorized modification of post content, including private or draft posts. Unauthenticated attackers could alter styling data, which may lead to unauthorized changes in sensitive information presentation or metadata. This could result in unauthorized access to or disclosure of personal data, violating GDPR's integrity and confidentiality principles or HIPAA's safeguards for protected health information.

Mitigation Strategies

Update the Themify Builder plugin to the latest version beyond 7.8.0 immediately to patch the authorization bypass vulnerability.
