Axios HTTP/2 Session Cleanup State Corruption Vulnerability

CVE-2026-39865 / GHSA-qj83-cq47-w5f8

More information

Details

Summary

Axios HTTP/2 session cleanup logic contains a state corruption bug that allows a malicious server to crash the client process through concurrent session closures. This denial-of-service vulnerability affects axios versions prior to 1.13.2 when HTTP/2 is enabled.

Details

The vulnerability exists in the Http2Sessions.getSession() method in lib/adapters/http.js. The session cleanup logic contains a control flow error when removing sessions from the sessions array.

Vulnerable Code:

while (i--) {
  if (entries[i][0] === session) {
    entries.splice(i, 1);
    if (len === 1) {
      delete this.sessions[authority];
      return;
    }
  }
}

Root Cause:
After calling entries.splice(i, 1) to remove a session, the original code only returned early if len === 1. For arrays with multiple entries, the iteration continued after modifying the array, causing undefined behavior and potential crashes when accessing shifted array indices.

Fixed Code:

while (i--) {
  if (entries[i][0] === session) {
    if (len === 1) {
      delete this.sessions[authority];
    } else {
      entries.splice(i, 1);
    }
    return;
  }
}

The fix restructures the control flow to immediately return after removing a session, regardless of whether the array is being emptied or just having one element removed. This prevents continued iteration over a modified array and eliminates the state corruption vulnerability.

Affected Component:

  • lib/adapters/http.js - Http2Sessions class, session cleanup in connection close handler
PoC
  1. Set up a malicious HTTP/2 server that accepts multiple concurrent connections from an axios client
  2. Establish multiple concurrent HTTP/2 sessions with the axios client
  3. Close all sessions simultaneously with precise timing
  4. The flawed cleanup logic attempts to iterate over and modify the sessions array concurrently
  5. This causes the client to access invalid memory locations, resulting in a process crash

Prerequisites:

  • Client must use axios with HTTP/2 enabled
  • Client must connect to attacker-controlled HTTP/2 server
  • Multiple concurrent HTTP/2 sessions must be established
  • Server must close all sessions simultaneously with precise timing
Impact

Who is impacted:

  • Applications using axios with HTTP/2 enabled
  • Applications connecting to untrusted or attacker-controlled HTTP/2 servers
  • Node.js applications using axios for HTTP/2 requests

Impact Details:

  • Denial of Service: Malicious server can crash the axios client process by accepting and closing multiple concurrent HTTP/2 connections simultaneously
  • Availability Impact: Complete loss of availability for the client process through crash (though service may auto-restart)
  • Scope: Impact is limited to the single client process making the requests; does not escape to affect other components or systems
  • No Confidentiality or Integrity Impact: Vulnerability only causes process crash, no information disclosure or data modification

Axios has a NO_PROXY Hostname Normalization Bypass Leads to SSRF

CVE-2025-62718 / GHSA-3p68-rc4w-qgx5

More information

Details

Axios does not correctly handle hostname normalization when checking NO_PROXY rules.
Requests to loopback addresses like localhost. (with a trailing dot) or [::1] (IPv6 literal) skip NO_PROXY matching and go through the configured proxy.

This goes against what developers expect and lets attackers force requests through a proxy, even if NO_PROXY is set up to protect loopback or internal services.

According to RFC 1034 §3.1 and RFC 3986 §3.2.2, a hostname can have a trailing dot to show it is a fully qualified domain name (FQDN). At the DNS level, localhost. is the same as localhost.
However, Axios does a literal string comparison instead of normalizing hostnames before checking NO_PROXY. This causes requests like http://localhost.:8080/ and http://[::1]:8080/ to be incorrectly proxied.

This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections.

PoC

import http from "http";
import axios from "axios";

const proxyPort = 5300;

http.createServer((req, res) => {
  console.log("[PROXY] Got:", req.method, req.url, "Host:", req.headers.host);
  res.writeHead(200, { "Content-Type": "text/plain" });
  res.end("proxied");
}).listen(proxyPort, () => console.log("Proxy", proxyPort));

process.env.HTTP_PROXY = `http://127.0.0.1:${proxyPort}`;
process.env.NO_PROXY = "localhost,127.0.0.1,::1";

async function test(url) {
  try {
    await axios.get(url, { timeout: 2000 });
  } catch {}
}

setTimeout(async () => {
  console.log("\n[*] Testing http://localhost.:8080/");
  await test("http://localhost.:8080/"); // goes through proxy

  console.log("\n[*] Testing http://[::1]:8080/");
  await test("http://[::1]:8080/"); // goes through proxy
}, 500);

Expected: Requests bypass the proxy (direct to loopback).
Actual: Proxy logs requests for localhost. and [::1].

Impact

  • Applications that rely on NO_PROXY=localhost,127.0.0.1,::1 for protecting loopback/internal access are vulnerable.

  • Attackers controlling request URLs can:

    • Force Axios to send local traffic through an attacker-controlled proxy.
    • Bypass SSRF mitigations relying on NO_PROXY rules.
    • Potentially exfiltrate sensitive responses from internal services via the proxy.

Affected Versions

  • Confirmed on Axios 1.12.2 (latest at time of testing).
  • affects all versions that rely on Axios’ current NO_PROXY evaluation.

Remediation
Axios should normalize hostnames before evaluating NO_PROXY, including:

  • Strip trailing dots from hostnames (per RFC 3986).
  • Normalize IPv6 literals by removing brackets for matching.

Severity

  • CVSS Score: 9.3 / 10 (Critical)
  • Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:H/SI:L/SA:L
