Lè w analize header Next.js ak konsistans ZXCVFIXVIBETOKEN1ZXCV atravè diferan pwofondè chemen, ZXCVFIXVIBETOKEN4ZXCV ka idantifye twou vid ki genyen nan konfigirasyon ZXCVFIXVIBETOKEN2ZXCV.

Next.js applications using next.config.js for header management are susceptible to security gaps if path-matching patterns are imprecise. This research explores how wildcard and regex misconfigurations lead to missing security headers on sensitive routes and how to harden the configuration.

CWE-1021CWE-200

Impact

Missing security headers can be exploited to perform clickjacking, cross-site scripting (XSS), or gather information about the server environment [S2]. When headers such as Content-Security-Policy (CSP) or X-Frame-Options are inconsistently applied across routes, attackers can target specific unprotected paths to bypass site-wide security controls [S2].

Root Cause

Next.js allows developers to configure response headers in next.config.js using the headers property [S2]. This configuration uses path matching that supports wildcards and regular expressions [S2]. Security vulnerabilities typically arise from:

  • Incomplete Path Coverage: Wildcard patterns (e.g., /path*) may not cover all intended subroutes, leaving nested pages without security headers [S2].
  • Information Disclosure: By default, Next.js may include the X-Powered-By header, which reveals the framework version unless explicitly disabled via the poweredByHeader configuration [S2].
  • CORS Misconfiguration: Improperly defined Access-Control-Allow-Origin headers within the headers array can allow unauthorized cross-origin access to sensitive data [S2].

Concrete Fixes

  • Audit Path Patterns: Ensure all source patterns in next.config.js use appropriate wildcards (e.g., /:path*) to apply headers globally where necessary [S2].
  • Disable Fingerprinting: Set poweredByHeader: false in next.config.js to prevent the X-Powered-By header from being sent [S2].
  • Restrict CORS: Set Access-Control-Allow-Origin to specific trusted domains rather than wildcards in the headers configuration [S2].

How FixVibe tests for it

FixVibe could perform an active gated probe by crawling the application and comparing the security headers of various routes. By analyzing the X-Powered-By header and the consistency of Content-Security-Policy across different path depths, FixVibe can identify configuration gaps in next.config.js.
