Executive Summary

The Beaver Builder Plugin (Starter Version) for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'auto_play' parameter in all versions up to 2.9.2.1. This occurs because the plugin does not properly sanitize input or escape output, allowing authenticated users with Contributor-level access or higher to inject malicious scripts into pages. These scripts execute whenever any user accesses the infected page.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access to inject malicious scripts that execute in the browsers of users who visit the affected pages. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed on behalf of the user without their consent.
