# CVE-2026-13162: CVE-2026-13162

Status: published. Published: 2026-10-27. Updated: 2026-11-04.

An OS command vulnerability exists in CoreTec product that allows authenticated users with certain roles to execute arbitrary system commands with full control over the device. The vulnerability exists in the configuration daemon's time synchronization handler, which is responsible for setting the system time-zone. When processing time-zone configuration updates, the daemon constructs a shell command by concatenating user-supplied input without any sanitization or validation.
