Vulnerability Overview

The Avada theme for WordPress is vulnerable to Stored Cross-Site Scripting via the update_layout function in versions up to, and including, 6.2.3 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers, and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 6.2.3, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
