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 'target' parameter of the plugin's bt_bb_icon shortcode in all versions up to, and including, 5.7.2 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 (XSS) vulnerability in the 'target' parameter of its bt_bb_icon shortcode. This flaw exists in versions up to 5.7.2 due to insufficient input sanitization and output escaping. Authenticated attackers with Contributor-level access or higher can exploit this to inject malicious scripts into pages.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Bold Page Builder plugin for versions up to 5.7.2. Check for suspicious scripts in pages using the bt_bb_icon shortcode. Review server logs for unusual activity related to the 'target' parameter.

Impact Analysis

If exploited, this vulnerability allows attackers to inject arbitrary web scripts into pages. When users access these pages, the injected scripts execute, potentially stealing user data, session cookies, or performing actions on behalf of the user. This could lead to unauthorized access or control of the affected WordPress site.

Compliance Impact

This vulnerability could compromise user data confidentiality, which is critical for GDPR and HIPAA compliance. If exploited, it may lead to unauthorized data access or breaches, resulting in potential violations of these regulations. Organizations must address this to maintain compliance and avoid penalties.

Mitigation Strategies

Update the Bold Page Builder plugin to the latest version. If an update is unavailable, disable the plugin immediately. Restrict Contributor-level access to prevent unauthorized script injection. Monitor pages using the bt_bb_icon shortcode for unexpected changes.
