How to fix?

Upgrade Oracle:8 nodejs-libs to version 1:24.14.1-2.module+el8.10.0+90873+35652ecc or higher.
This issue was patched in ELSA-2026-7670.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs-libs package and not the nodejs-libs package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
