Stored XSS in Bold Page Builder WordPress Plugin

Publication date: 2026-09-30

Last updated on: 2026-09-30

Assigner: Wordfence

Description
The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `title` attribute of the `bt_bb_service` shortcode in all versions up to, and including, 5.7.2. This is due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

The Bold Page Builder plugin for WordPress has a stored cross-site scripting vulnerability in versions up to 5.7.2. It allows authenticated attackers with Contributor-level access or higher to inject malicious scripts via the title attribute of the bt_bb_service shortcode. The issue arises from insufficient input sanitization and output escaping.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Bold Page Builder plugin for versions up to 5.7.2. Check for injected scripts in pages using the bt_bb_service shortcode with malicious title attributes. Review server logs for unusual script executions or unauthorized page edits by Contributor-level users or above.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into WordPress pages. When users access these pages, the scripts execute, potentially stealing user data, session cookies, or performing actions on behalf of the user. It requires at least Contributor-level access to exploit.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR and HIPAA compliance. GDPR requires protecting user data, while HIPAA mandates safeguarding protected health information. Exploitation may result in data breaches, leading to legal penalties and reputational damage.

Mitigation Strategies

Immediately update the Bold Page Builder plugin to the latest version beyond 5.7.2. Remove or sanitize any existing malicious scripts in pages using the bt_bb_service shortcode. Restrict Contributor-level and higher user roles to prevent unauthorized edits. Monitor pages for further unauthorized changes.
