the main user account has restricted privileges but is in the sudoers group and there is not any mechanism in place to prevent sudo su or sudo -i to be run gaining unrestricted access to sensible files, encryption, or issue orders that disrupt robot operation.

Exploit prediction

0.74% chance of exploitation in the next 30 days, higher than 55% of all scored CVEs (FIRST EPSS, 2026-11-08).
