• #14460 008dc75 Thanks @florian-lefebvre! - Fixes a case where astro:config/server values typed as URLs would be serialized as strings

• #13730 7260367 Thanks @razonyang! - Fixes a bug in i18n, where Astro caused an infinite loop when a locale that doesn't have an index, and Astro falls back to the index of the default locale.

• 6ee63bf Thanks @matthewp! - Adds security.allowedDomains configuration to validate X-Forwarded-Host headers in SSR

  The X-Forwarded-Host header will now only be trusted if it matches one of the configured allowed host patterns. This prevents host header injection attacks that can lead to cache poisoning and other security vulnerabilities.

  Configure allowed host patterns to enable X-Forwarded-Host support:

  // astro.config.mjs
  export default defineConfig({
    output: 'server',
    adapter: node(),
    security: {
      allowedDomains: [
        { hostname: 'example.com' },
        { hostname: '*.example.com' },
        { hostname: 'cdn.example.com', port: '443' },
      ],
    },
  });

  The patterns support wildcards (* and **) for flexible hostname matching and can optionally specify protocol and port.

  Breaking change

  Previously, Astro.url would reflect the value of the X-Forwarded-Host header. While this header is commonly used by reverse proxies like Nginx to communicate the original host, it can be sent by any client, potentially allowing malicious actors to poison caches with incorrect URLs.

  If you were relying on X-Forwarded-Host support, add security.allowedDomains to your configuration to restore this functionality securely. When allowedDomains is not configured, X-Forwarded-Host headers are now ignored by default.
