Beaver Builder Page Builder – Drag and Drop Website Builder < 2.10.1.2 - Authenticated (Author+) Stored Cross-Site Scripting via 'settings[js]'

Description

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.
