Node.js Module axios 0.31.1 < 0.33.0 / 1.15.2 < 1.18.0 Proxy Hijacking (CVE-2026-67320)

high Nessus Plugin ID 333250

Synopsis

A module in the Node.js JavaScript run-time environment is affected by a proxy hijacking vulnerability.

Description

The version of the axios Node.js module installed on the remote host is 0.31.1 prior to 0.33.0 or 1.15.2 prior to 1.18.0. It is, therefore, affected by a vulnerability:

 - axios in a Node.js deployment using the HTTP adapter can route requests through an attacker-controlled proxy. Request interceptors run after the merge and a common immutable interceptor pattern converts the hardened config back into a regular object. The Node HTTP adapter then reads config.proxy through the prototype chain, allowing an attacker who can pollute Object.prototype.proxy to observe Authorization headers, Basic auth, and request bodies on plaintext HTTP requests. (CVE-2026-67320)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to axios version 0.33.0 / 1.18.0 or later.
