CVE-2026-65643Network attack vector

Root code execution via domain parking eval injection

Published Sep 1, 2026 · Updated Sep 2, 2026

Eval injection in WebPros cPanel allows remote authenticated users to execute arbitrary code as root through domain parking operations. The domain parking path evaluates attacker-controlled directives without adequate neutralization, enabling arbitrary file creation on the server. Exploitation requires a cPanel account allowed to add parked or addon domains and grants control over every hosted account, website, and database.
