Stored script execution via unescaped form setting
Published Dec 11, 2023 · Updated Oct 1, 2024
Stored XSS in CodePeople Contact Form Email before 1.3.44 allows remote authenticated users to execute script in visitors' browsers. The post-submit classic-message setting stores an unescaped closing script tag and later embeds it in a published form page. An administrator without unfiltered_html permission can plant the payload; viewing the published form executes it in visitors' sessions.
