Bold Page Builder Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Bold Page Builder plugin for WordPress, affecting all versions through 5.6.8. The issue arises from inadequate input sanitization and output escaping for user-supplied attributes, particularly the 'text' attribute of the bt_bb_button shortcode. This vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages, which are executed when users access the affected pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users are advised to update the Bold Page Builder plugin to version 5.6.9 or a newer patched version.
