CVE-2025-31821Network attack vector

Unauthenticated phishing via open redirect

Published Apr 1, 2025 · Updated May 10, 2025

Open redirect in Forms Integrations Integration of Zoho CRM and Contact Form 7 1.0.6 and earlier allows remote attackers to conduct phishing. Published records do not identify the endpoint, parameter, or redirect routine that accepts an attacker-controlled destination. Exploitation requires a user to follow a crafted link, after which the trusted site redirects the browser to an attacker-chosen location and enables limited information exposure.
