CVE-2025-15241Public exploitNetwork attack vector

Authenticated open redirect via unvalidated Referer header

Published Dec 30, 2025 · Updated Dec 30, 2025

Open redirect in CloudPanel Community Edition 2.5.0 through 2.5.1 allows remote authenticated users to redirect browsers via Referer. The /admin/users handler copies an unvalidated Referer value into the Location header of a 302 response. A low-privileged session and user interaction are required; a crafted link can send the browser to an attacker-controlled site for phishing.
