Azure Linux 3.0 Security Update: nodejs (CVE-2025-23083)

high Nessus Plugin ID 295525

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of nodejs installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-23083 advisory.

 - With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread is created. This is not limited only to workers but also exposes internal workers, where an instance of them can be fetched, and its constructor can be grabbed and reinstated for malicious usage. This vulnerability affects Permission Model users (--permission) on Node.js v20, v22, and v23. (CVE-2025-23083)

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

Solution

Update the affected packages.
