The Beaver Builder Page Builder WordPress plugin suffers from a stored cross-site scripting vulnerability via the 'settings[js]' parameter due to improper input neutralization. This allows authenticated users with author or higher privileges to inject arbitrary JavaScript code into pages, which executes in the context of users viewing those pages. The vulnerability affects versions up to 2.10.1.1. The CVSS 3.1 score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the author level. No official fix or patch has been published as of the data provided.

Successful exploitation allows an authenticated author-level user to inject persistent malicious scripts into pages. These scripts execute in the browsers of users who view the compromised pages, potentially leading to session hijacking, unauthorized actions, or other client-side impacts. The vulnerability does not impact availability and has limited confidentiality and integrity impact as per the CVSS vector. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict author-level access to trusted users only and consider monitoring for suspicious activity related to page content changes. Avoid granting author or higher privileges to untrusted users to reduce risk.
