Authenticated host command execution via incomplete validation
Published Jun 11, 2026 · Updated Jun 11, 2026
OS command injection in CyberArk Privileged Session Manager for SSH allows remote authenticated users to execute commands on its Linux host. CyberArk attributes the flaw to incomplete input validation but has not identified the input field, handler, or command-construction path that passes attacker-controlled text to the operating system. A low-privileged PSMP account and network access are required; successful exploitation executes arbitrary commands on the host within the broker process's permissions.
