CVE-2026-29203

A chmod call in the cPanel Nova plugin's Cpanel::Nova::Connector follows symlinks, allowing setting root permissions on arbitrary system files or directories. That can cause DoS or local privilege escalation when an authenticated cPanel user places a symlink at a user-controlled legacy Nova path under their home directory.
