SCA: security update for undici (GHSA-phc3-fgpg-7m6h)

medium Tenable Cloud Security Plugin ID 438788

Description

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

 - This is an uncontrolled resource consumption vulnerability (CWE-400) that can lead to Denial of Service
 (DoS). In vulnerable Undici versions, when interceptors.deduplicate() is enabled, response data for
 deduplicated requests could be accumulated in memory for downstream handlers. An attacker-controlled or
 untrusted upstream endpoint can exploit this with large/chunked responses and concurrent identical
 requests, causing high memory usage and potential OOM process termination. Impacted users are applications
 that use Undici’s deduplication interceptor against endpoints that may produce large or long-lived
 response bodies. PatchesThe issue has been patched by changing deduplication behavior to stream response
 chunks to downstream handlers as they arrive (instead of full-body accumulation), and by preventing late
 deduplication when body streaming has already started. Users should upgrade to the first official Undici
 (and Node.js, where applicable) releases that include this patch. (CVE-2026-2581)

Solution

Update the undici library and its related packages to version 7.24.0 or later.
