CVE-2024-9614Network attack vector

Reflected XSS via unescaped add_query_arg URLs

Published Nov 13, 2024 · Updated Apr 8, 2026

Reflected XSS in Mailmunch Constant Contact Forms by MailMunch 2.1.2 and earlier allows remote attackers to inject scripts via crafted URLs. The admin integration template calls add_query_arg for URL values and emits the results without appropriate output escaping. No account is required, but a victim must follow an attacker-crafted link and render the affected page; the resulting script runs in that user's browser.
