Echo: axios: security update to 0.31.1

low Tenable Self-Hosted Container Security Plugin ID 457148

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, the encode()
 function in lib/helpers/AxiosURLSearchParams.js contains a character mapping (charMap) at line 21 that
 reverses the safe percent-encoding of null bytes. After encodeURIComponent('\x00') correctly produces the
 safe sequence %00, the charMap entry '%00': '\x00' converts it back to a raw null byte. Primary impact is
 limited because the standard axios request flow is not affected. This vulnerability is fixed in 1.15.1 and
 0.31.1. (CVE-2026-42040)

Solution

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