Stored XSS in Beaver Builder WordPress Plugin

Publication date: 2026-08-15

Last updated on: 2026-08-15

Assigner: Wordfence

Description
The Beaver Builder Page Builder – Drag and Drop Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Button Module 'button' (Button Code) Setting in all versions up to, and including, 2.10.2.2 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. Beaver Builder grants editor access to any WordPress role holding the edit_posts capability by default, meaning Author-level users and above can exploit this vulnerability.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Beaver Builder Page Builder plugin for WordPress. It exists in versions up to 2.10.2.2 due to insufficient input sanitization and output escaping in the Button Module's 'button' setting. Authenticated attackers with author-level access or higher can inject malicious scripts into pages.

Detection Guidance

Check WordPress plugins for Beaver Builder versions up to 2.10.2.2. Inspect Button Module settings for injected scripts in button code fields. Review user roles with edit_posts capability for unauthorized access.

Impact Analysis

If exploited, this vulnerability allows attackers to inject arbitrary web scripts into pages. When users access these pages, the scripts execute, potentially stealing user data, session cookies, or performing actions on behalf of the user. This could lead to unauthorized access, data breaches, or defacement of websites.

Compliance Impact

This vulnerability could lead to data breaches, which may violate GDPR and HIPAA requirements for protecting user data. Organizations using the affected plugin may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Update Beaver Builder to the latest version beyond 2.10.2.2. Remove or restrict Author-level and higher user roles if not needed. Scan WordPress sites for malicious scripts in Button Module button code settings.
