CVE-2024-48021Network attack vector

Script execution via undisclosed reflected input

Published Oct 17, 2024 · Updated Apr 28, 2026

Reflected XSS in Contact Form 7 – PayPal & Stripe Add-on 2.3 and earlier allows remote attackers to run script in a privileged user's browser. Public advisories do not identify the affected request parameter or the output operation that reflects it without neutralization. Exploitation is unauthenticated but requires a privileged user to open crafted content, exposing that browser session to injected script.
