What is CVE-2026-6172?

The Bold Page Builder plugin for WordPress is susceptible to a stored cross-site scripting vulnerability through the 'caption' parameter of its bt_bb_image shortcode. This issue arises from inadequate input sanitization and output escaping concerning user-supplied attributes. As a result, authenticated attackers with Contributor-level access and above can inject arbitrary web scripts into the plugin, which can then execute when users access affected pages. Ensuring your WordPress installation is updated is crucial for mitigating this risk and enhancing web application security.

Affected Version(s)

Bold Page Builder 0 <= 5.7.2
