CVE-2026-84021 Details
Description
The Bold Page Builder WordPress plugin before 5.9.8 does not properly validate a link URL before outputting it in an HTML attribute, relying on a filter that can be evaded, allowing users with the Contributor role and above to inject arbitrary web scripts that execute when a user clicks the affected link.
A stored cross-site scripting vulnerability has been identified in the Bold Page Builder WordPress plugin, affecting versions prior to 5.9.8. The issue arises because the plugin fails to properly validate link URLs before inserting them into HTML attributes. This flaw allows users with Contributor roles and above to inject arbitrary web scripts that execute when the link is clicked. The vulnerability can be exploited through the 'bt_bb_button', 'bt_bb_headline', or 'bt_bb_icon' URL attributes, all of which are affected by the same validation issue.
Users are advised to update the Bold Page Builder WordPress plugin to version 5.9.8 or later.
