Echo: undici: security update to 6.24.0

medium Tenable Self-Hosted Container Security Plugin ID 459907

Description

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

 - ImpactWhen an application passes user-controlled input to the upgrade option of client.request(), an
 attacker can inject CRLF sequences (\r\n) to: * Inject arbitrary HTTP headers * Terminate the HTTP request
 prematurely and smuggle raw data to non-HTTP services (Redis, Memcached, Elasticsearch) The vulnerability
 exists because undici writes the upgrade value directly to the socket without validating for invalid
 header characters: // lib/dispatcher/client-h1.js:1121 if (upgrade) { header += `connection:
 upgrade\r\nupgrade: ${upgrade}\r\n` } (CVE-2026-1527)

Solution

Update the undici library and its related packages to version 6.24.0 or later.
