ℹī¸ About CORS Vulnerabilities

CORS (Cross-Origin Resource Sharing) misconfigurations can allow malicious websites to read sensitive data from your API. Common issues include reflecting the Origin header without validation, allowing null origins, and exposing credentials to any origin. This tool checks response headers to identify potential vulnerabilities.

Note: Due to browser security restrictions, this client-side scanner has limited capabilities. For comprehensive testing, use a server-side tool or BurpSuite.
