Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unsanitized control characters in redirect URLs can cause the Node.js HTTP response headers to fail validation, triggering unhandled exceptions that crash the entire server process (CVE-2019-10775).
Denial of Service: Misconfiguration of server authorization parameters combined with malformed Authorization headers can trigger unhandled runtime exceptions during credential parsing, resulting in a denial of service.
Prototype Pollution: The use of deprecated command-line argument parsing libraries (specifically 'optimist') allows malicious input parameters to pollute the global Object prototype, potentially leading to remote code execution or property injection.
