high Nessus Plugin ID 309956

Synopsis

A module in the Node.js JavaScript run-time environment is affected by a denial of service vulnerability.

Description

The nodejs module Undici detected on the host is version 6.x prior to 6.24.0 or version 7.x prior to 7.24.0. It is, therefore, affected by a denial of service vulnerability :

- A flaw exists in the WebSocket client due to an integer overflow when processing frames with extremely large 64-bit length values. An unauthenticated, remote attacker can exploit this to cause denial of service via process termination. (CVE-2026-1528)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Undici version 6.24.0 / 7.24.0 or later.
