CVE-2025-12834Network attack vectorHinoki check available

Reflected XSS via unescaped failure message

Published Dec 12, 2025 · Updated Dec 12, 2025

Reflected XSS in ZealousWeb Accept Stripe Payments Using Contact Form 7 3.1 and earlier allows remote attackers to inject scripts. The plugin's class.cf7sa.lib.php payment-failure path reads the failure_message request parameter and renders it without sufficient sanitization or output escaping. Execution requires a victim to follow an attacker-crafted link, and the resulting script runs in that visitor's browser context.
