Upgrade github.com/jmpsec/osctrl/cmd/admin to version 0.5.0 or higher.
Overview
Affected versions of this package are vulnerable to Command Injection in the osctrl-admin environment configuration. An attacker can execute arbitrary shell commands on every endpoint that enrolls using a compromised environment by injecting commands into the hostname parameter, which are then embedded in enrollment scripts and executed with elevated privileges before agent installation. This enables actions such as backdoor installation, credential exfiltration, and full endpoint compromise.
