CVE-2025-13087Network attack vector

Administrator-level root command execution via header injection

Published Nov 20, 2025 · Updated Nov 20, 2025

OS command injection in Opto 22 groov EPIC and groov RIO firmware 3.2.0 through 4.0.2 allows remote authenticated users to execute commands as root. A vulnerable groov Manage REST endpoint reads attacker-controlled HTTP header values and uses them to construct operating-system commands without neutralization. Exploitation requires System-Wide Administrator permission and grants root-level command execution on the appliance.
