What the vulnerability does
01Description
The Beaver Builder Page Builder – Drag and Drop Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `js` Global Settings parameter in all versions up to, and including, 2.10.0.5 due to missing capability checks on save_global_settings() function and insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Custom-level access and above who have been granted beaver builder access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
