CVE-2025-61984
Description
ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used.

(A configuration file that provides a complete literal username is not categorized as an untrusted source.)
