CVE-2026-92084

critical

Description

The The Beaver Builder Page Builder – Drag and Drop Website Builder plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.11.0.5. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires the target site to have a Beaver Builder page containing the Sidebar module populated with a widget that displays attacker-controllable text, such as the core Recent Comments widget, with comment moderation disabled or the attacker's comment approved.
