The `sshNodeCommand` function in `CommandResolver.swift` builds a shell script for remote execution. When setting the remote directory via cd
</code>, a failure triggers an error message constructed as <code>echo "cd failed for path: [bash]"</code>. The project path is inserted without any sanitization or escaping. If an attacker supplies a path like <code>fake_path; malicious_command</code>, the `echo` statement will execute the embedded command on the remote SSH host due to improper interpolation into the shell script context. Simultaneously, the `parseSSHTarget` function fails to validate the structure of the SSH target string. Standard SSH clients treat arguments beginning with a dash (<code>-</code>) as command-line flags, not hostnames. By supplying a target such as <code>-oProxyCommand=sh -c 'malicious_command'</code>, the application passes this string directly to the underlying SSH command. The SSH client interprets it as a configuration flag, executing the specified proxy command on the local machine immediately during connection initiation, leading to local command execution.

// Simplified vulnerable code snippet from CommandResolver.swift let errorScript = """ cd (userProjectPath) if [ $? -ne 0 ]; then echo "cd failed for path: (userProjectPath)" exit 1 fi """
How Exploit:
Social engineering to inject malicious path or SSH target into app config.
Remote execution via unescaped `userProjectPath` in `echo`.
Local execution via dash-prefixed SSH target parsed as flag.
Protection from this CVE
Implement strict input validation.
Escape all user inputs in shell contexts.
Reject SSH targets starting with "-".
Impact:
Arbitrary code execution.
Local or remote host compromise.
Full system control potential.
