Remediation Patch

Disable X-Powered-By in Next.js

patch.diff (javascript)

--- a/handler.javascript (Vulnerable)

// default next.config.js emits x-powered-by

+++ b/handler.javascript (Remediated)

module.exports = { poweredByHeader: false };

Disable verbose headers to prevent automated vulnerability scanners from immediately identifying unpatched versions.
