CVE-2023-2518Public exploitNetwork attack vector

Administrator-session script execution via unescaped error parameter

Published May 30, 2023 · Updated Jan 10, 2025

Reflected XSS in Easy Forms for Mailchimp before 6.8.9 allows remote attackers to run scripts in an administrator's browser. With debug mode enabled, the edit-form admin page writes the sql_error query parameter into HTML without sanitization or output escaping. An administrator must be logged in and open a crafted URL; successful exploitation runs attacker-controlled script in that privileged WordPress session.
