The Beaver Builder Page Builder - Drag and Drop Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'settings[js]' parameter in versions up to, and including, 2.10.1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored Cross-Site Scripting in Beaver Builder Page Builder plugin for WordPress up to version 2.10.1.1 allows authenticated attackers with author-level access or higher to inject arbitrary JavaScript through the 'settings[js]' parameter due to insufficient input sanitization and output escaping. When injected pages are accessed by other users, the malicious scripts execute in their browsers, potentially compromising site integrity and user accounts. No public exploit code or active CISA KEV status reported at analysis time.
Technical ContextAI
Beaver Builder Page Builder is a WordPress plugin (CPE: cpe:2.3:a:beaverbuilder:beaver_builder_page_builder_-_drag_and_drop_website_builder) that provides drag-and-drop page building functionality. The vulnerability stems from CWE-79 (Improper Neutralization of Input During Web Page Generation, also known as Cross-site Scripting) in the 'settings[js]' parameter handling. The plugin fails to properly sanitize user input before storing it in the database and does not adequately escape output when rendering the stored data. This allows authenticated users to bypass input validation and inject JavaScript payloads that persist in the database and execute in the context of other users' browsers, particularly high-risk because it affects the page-building configuration layer where security controls may be weaker than in main content areas.
RemediationAI
Update Beaver Builder Page Builder plugin to a version newer than 2.10.1.1 where input sanitization and output escaping have been remediated. Site administrators should immediately patch the plugin via WordPress admin dashboard (Plugins > Updates) or by downloading the latest version from https://www.wpbeaverbuilder.com/change-logs/. As an interim measure before patching, restrict author-level and above access to users with demonstrable need, audit existing pages and templates for suspicious JavaScript in builder settings, and monitor user activity for unauthorized modifications.
