CVE-2026-29203
HighSummary
A chmod call in the cPanel Nova plugin's Cpanel::Nova::Connector follows symlinks, allowing setting root permissions on arbitrary system files or directories. This can lead to DoS or local privilege escalation when an authenticated cPanel user places a symlink at a user-controlled legacy Nova path under their home directory.
Risk Assessment
The organization may be exposed to attacks that lead to privilege escalation or disruption of system functionality, potentially affecting service availability.
Recommendation
It is recommended to restrict access to the cPanel Nova plugin and to monitor and audit symlinks in user directories to prevent unauthorized permission changes.
