CVE-2026-88037

Name of the Vulnerable Software and Affected Versions Bold Page Builder versions prior to 5.7.3

Description Stored Cross-Site Scripting occurs due to insufficient input sanitization and output escaping on user supplied attributes. Authenticated attackers with Contributor-level access and above can inject arbitrary web scripts via the title attribute of the bt bb service shortcode. These scripts execute whenever a user accesses the affected page.

Recommendations Update Bold Page Builder to version 5.7.3 or later. As a temporary mitigation, restrict the ability of users with Contributor-level access to edit pages or use the bt bb service shortcode.
