libssh.so is vulnerable to Command Injection. The vulnerability is due to insufficient validation of the hostname parameter in the URI parsing process. This allows attackers to use ProxyCommand or the ProxyJump features to exploit and inject malicious code via the unchecked hostname parameter on the client.
