WalkthroughThe update introduces new logic in the request handling process for the "/login" path. When a request's URL pathname starts with "/login", the server sets two security headers— Changes

28-33: LGTM! Good security enhancement.The implementation correctly sets both X-Frame-Options and CSP frame-ancestors headers, providing robust clickjacking protection through defense in depth.
Consider enhancing security headers further.
- Consider applying these headers globally instead of just the login path.
- Consider adding Strict-Transport-Security (HSTS) header.
- Consider expanding CSP with additional directives like default-src, script-src, etc.
Here's how you could enhance the security headers:
const url = new URL(request.url); - if (url.pathname.startsWith("/login")) { - responseHeaders.set("X-Frame-Options", "SAMEORIGIN"); - responseHeaders.set("Content-Security-Policy", "frame-ancestors 'self'"); - } + // Set security headers for all routes + responseHeaders.set("X-Frame-Options", "SAMEORIGIN"); + responseHeaders.set("Content-Security-Policy", + "default-src 'self';" + + "frame-ancestors 'self';" + + "script-src 'self' 'unsafe-inline' 'unsafe-eval';" + + "style-src 'self' 'unsafe-inline';" + + "img-src 'self' data: https:;" + + "connect-src 'self' https:;" + ); + responseHeaders.set("Strict-Transport-Security", + "max-age=31536000; includeSubDomains" + );
