CVE-2026-67609Public exploit

Root command execution via unrestricted sudo nice

Published Aug 3, 2026 · Updated Aug 3, 2026

Privilege escalation in Telenia Software TVox 24.0.0 through 24.9.21 and 26.0.0 through 26.5.3 allows local users to execute commands as root. The /etc/sudoers.d/telenia file grants the apache account passwordless sudo execution of /bin/nice, which preserves root privileges for a supplied command. Access to the apache account is required, after which arbitrary commands run as root without user interaction.
