What the vulnerability does
The Beaver Builder – WordPress Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the audio widget 'link_url' parameter in all versions up to, and including, 2.7.4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms

The vulnerability has a changed scope, meaning injected code can affect other users and site functionality beyond the vulnerable component. An attacker with low-level site access can craft malicious input that executes in other users' browsers when they view affected pages.
What an attacker can do
Inject JavaScript that runs in other users' browsers and affects site functionality.
