Echo: axios: security update to 0.31.1

high Tenable Cloud Security Plugin ID 462320

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, a prototype
 pollution gadget exists in the Axios HTTP adapter (lib/adapters/http.js) that allows an attacker to inject
 arbitrary HTTP headers into outgoing requests. The vulnerability exploits duck-type checking of the data
 payload, where if Object.prototype is polluted with getHeaders, append, pipe, on, once, and
 Symbol.toStringTag, Axios misidentifies any plain object payload as a FormData instance and calls the
 attacker-controlled getHeaders() function, merging the returned headers into the outgoing request. The
 vulnerable code resides exclusively in lib/adapters/http.js. The prototype pollution source does not need
 to originate from Axios itself — any prototype pollution primitive in any dependency in the application's
 dependency tree is sufficient to trigger this gadget. This vulnerability is fixed in 1.15.1 and 0.31.1.
 (CVE-2026-42035)

Solution

Update the axios library and its related packages to version 0.31.1 or later.
