SCA: security update for github.com/nats-io/nats-server/v2 (GHSA-v722-jcv5-w7mc)

high Tenable Self-Hosted Container Security Plugin ID 439162

Description

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

 - NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to
 versions 2.11.15 and 2.12.6, for MQTT deployments using usercodes/passwords: MQTT passwords are
 incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring
 endpoints. Versions 2.11.14 and 2.12.6 contain a fix. As a workaround, ensure monitoring end-points are
 adequately secured. Best practice remains to not expose the monitoring endpoint to the Internet or other
 untrusted network users. (CVE-2026-33216)

Solution

Update the github.com/nats-io/nats-server/v2 library and its related packages to version 2.11.15 or later.
