Description: A potential code injection vulnerability has been detected on this line, where untrusted input is passed to a method that may execute arbitrary code. This issue allows attackers to inject and execute arbitrary code within the application, which could lead to unauthorized access to sensitive data or other malicious actions. To mitigate this, ensure that all user-supplied input is properly sanitized and validated before being processed. Avoid passing untrusted input to methods like eval, send, or system that can execute arbitrary code. Where possible, use safer alternatives such as parameterized queries or more controlled methods for handling user input. Learn more

Severity: Critical

const filePath = path.join(outputDir, outputFile || '');

try {
child_process.execFileSync('curl', ['-o', filePath, url]);

Description: Path traversal vulnerability detected. User-controlled input in filesystem operations allows attackers to access files outside intended directories. This can lead to unauthorized access to sensitive system files and exposure of confidential data. To remediate: Use path.basename() to strip directory components, explicitly check for path traversal sequences "..", and validate final paths remain within authorized directories.

Description: Passing user-provided input directly to operating system command functions without validation introduces an OS command injection vulnerability. This allows attackers to inject and execute arbitrary commands on the host system. To remediate this, avoid constructing command lines using raw user input. Use the ProcessStartInfo class with ArgumentList to safely pass parameters without shell interpretation, and avoid calling cmd.exe /c when possible. Always validate or allowedlist input to ensure only safe values are used. Learn more: https://cwe.mitre.org/data/definitions/78.html
