Technical details
Incorrect permission assignment in cPanel's CalDAV/CardDAV implementation fails to properly isolate data between accounts. Local attackers with system-level access can enumerate and read calendar and contact data from other users' accounts without authentication. This is a classic privilege isolation failure in a multi-tenant hosting environment.
