Published 2026-02-25

OneUptime is a solution for monitoring and managing online services. Prior to version 10.0.7, an OS command injection vulnerability in `NetworkPathMonitor.performTraceroute()` allows any authenticated project user to execute arbitrary operating system commands on the Probe server by injecting shell metacharacters into a monitor's destination field. Version 10.0.7 fixes the vulnerability.
