CVE-2024-32884: gix-transport indirect code execution via malicious username

April 15, 2024 (updated July 5, 2024)

gix-transport does not check the username part of a URL for text that the external ssh program would interpret as an option. A specially crafted clone URL can smuggle options to SSH. The possibilities are syntactically limited, but if a malicious clone URL is used by an application whose current working directory contains a malicious file, arbitrary code execution occurs.
