Description

This module exploits a command injection vulnerability in Web-Check's `/api/screenshot` endpoint.
The `directChromiumScreenshot()` function uses `child_process.exec()` with unsanitized user input,
allowing command injection via URL query parameters. The vulnerability was patched in commit
0e4958aa10b2650d32439a799f6fc83a7cd46cef by replacing `exec()` with `execFile()`.
