AI Powered Q&A
Can you explain this vulnerability to me?
The Beaver Builder Page Builder plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 2.10.0.5. This vulnerability arises because the plugin's save_global_settings() function lacks proper capability checks and does not sufficiently sanitize or escape input and output related to the `js` Global Settings parameter.
As a result, authenticated users with Custom-level access or higher who have been granted access to Beaver Builder can inject arbitrary web scripts into pages. These scripts execute whenever any user accesses the affected page, potentially compromising user security.
How can this vulnerability impact me? :
This vulnerability allows attackers with certain authenticated access to inject malicious scripts into pages built with Beaver Builder. The impact includes:
- Execution of arbitrary JavaScript code in the context of users visiting the infected pages.
- Potential theft of user session cookies, leading to account hijacking.
- Defacement or manipulation of website content.
- Phishing attacks by injecting fake login forms or misleading content.
- Compromise of user data confidentiality and integrity.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

What immediate steps should I take to mitigate this vulnerability?
The vulnerability affects all versions of the Beaver Builder Page Builder plugin up to and including 2.10.0.5. It allows authenticated users with Custom-level access or higher who have Beaver Builder access to inject arbitrary scripts via the js Global Settings parameter due to missing capability checks and insufficient input sanitization.
Immediate mitigation steps include:
- Restrict Beaver Builder access only to trusted users with appropriate permissions.
- Update the Beaver Builder plugin to a version later than 2.10.0.5 where this vulnerability is fixed.
- Review and audit user roles and capabilities to ensure no unauthorized users have access to Beaver Builder features.
- Monitor and restrict the use of the save_global_settings() function or any interface that allows modification of the js Global Settings parameter.
