Vulnerability Overview

The Avada theme for WordPress is vulnerable to Stored Cross-Site Scripting via avada_portfolio_category_slug parameter saved by the save_permalink_settings() function called via 'admin_init' in versions up to 5.1.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 5.1.5, 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.
