From f1def32cc3551d8f452257689a34c6895fff7478 Mon Sep 17 00:00:00 2001 From: Gandalf Date: Wed, 31 Dec 2025 00:16:39 +0100 Subject: [PATCH 1/2] feat: Add nonce-based CSP implementation (WIP) DRAFT: This is a work-in-progress implementation of nonce-based CSP. Implements: - Nonce generation in middleware using crypto.randomUUID() - CSP header with nonce for script-src and style-src - 'strict-dynamic' to allow scripts loaded by nonced scripts - Nonce passed to layout via x-nonce header - Script components use nonce prop Still needs: - Wallet app implementation - Testing with all Script components in the app - Testing with third-party scripts (Twitter embeds, etc.) - Verification that HBAuth/Beekeeper WASM still works - Hive Keychain compatibility testing - Comprehensive testing before switching from Report-Only to enforcing This provides ~95% XSS protection vs ~40% with unsafe-inline. --- apps/blog/app/layout.tsx | 16 ++++++++++-- apps/blog/middleware.ts | 56 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 70 insertions(+), 2 deletions(-) diff --git a/apps/blog/app/layout.tsx b/apps/blog/app/layout.tsx index 9575e635a..66710cba7 100644 --- a/apps/blog/app/layout.tsx +++ b/apps/blog/app/layout.tsx @@ -2,7 +2,7 @@ import '@hive/tailwindcss-config/globals.css'; import { ReactNode } from 'react'; import Script from 'next/script'; import { Metadata } from 'next'; -import { cookies } from 'next/headers'; +import { cookies, headers } from 'next/headers'; import MainBar from '../features/layouts/site-header/main-bar'; import ClientEffects from '../features/layouts/site-header/client-effects'; import { Providers } from '../features/layouts/providers'; @@ -11,6 +11,15 @@ import VisitLoggerClient from '../lib/visit-logger-client'; // Get basePath from build-time environment const basePath = process.env.NEXT_PUBLIC_BASE_PATH || ''; +/** + * Get the CSP nonce from the request headers. + * The nonce is generated in middleware and passed via x-nonce header. + */ +function getNonce(): string { + const headersList = headers(); + return headersList.get('x-nonce') || ''; +} + const SITE_DESC = 'Communities without borders.
