CVE-2024-8492Public exploitNetwork attack vector

Visitor-side script execution via unescaped Validate setting

Published May 15, 2025 · Updated May 17, 2025

Stored cross-site scripting in WPMU DEV Hustle 7.8.5 and earlier allows remote authenticated users to run script in visitors' browsers. The popup email settings store the Validate field without sanitizing or escaping it, then render the value when a visitor submits invalid text. An Editor-level user can plant the payload even when unfiltered_html is disabled, but execution requires a visitor to interact with the affected popup.
