CVE-2026-65091Network attack vectorHinoki check available

Code execution via unescaped SSH session fields

Published Aug 25, 2026 · Updated Aug 25, 2026

OS command injection in NVIDIA OpenShell 0.0.33 and earlier allows attackers controlling a gateway to execute code on the client host. The CLI placed gateway-supplied SSH session response fields into an OpenSSH ProxyCommand without safe escaping or validation. Exploitation requires a user to initiate an SSH-backed sandbox operation against a malicious gateway, enabling local data access and tampering.
