Node.js Module axios 1.15.2 < 1.18.0 Prototype Pollution (CVE-2026-67314)

medium Nessus Plugin ID 333253

Synopsis

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

Description

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

 - Prototype-pollution read-side gadgets in Basic auth subfield handling. When an application is already affected by a separate prototype-pollution primitive and makes an axios request with an own auth object that omits the username and/or password properties, axios reads the inherited Object.prototype.username and Object.prototype.password values and uses them to construct an outbound Authorization Basic header.
 (CVE-2026-67314)

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 1.18.0 or later.
