CVE-2023-53158Public exploit

Command execution via SSH option injection

Published Jul 28, 2025 · Updated Jul 28, 2025

OS command injection in GitoxideLabs gix-transport before 0.36.1 allows attackers to execute commands through a crafted SSH clone URL. The SSH transport passes a URL host or path beginning with a hyphen to ssh as an operand, so ssh instead parses it as options such as ProxyCommand. Execution requires an application or local user to process the malicious URL; the published proof of concept launches a command on macOS.
