GHSA-V722-JCV5-W7MC
Vulnerability from github – Published: 2026-03-24 21:42 – Updated: 2026-03-27 22:09Background
NATS.io is a high performance open source pub-sub distributed communication technology, built for the cloud, on-premise, IoT, and edge computing.
The nats-server provides an MQTT client interface.
Problem Description
For MQTT deployments using usercodes/passwords: MQTT passwords are incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring endpoints.
Affected Versions
Any version before v2.12.6 or v2.11.15
Workarounds
Ensure monitoring end-points are adequately secured.
Best practice remains to not expose the monitoring endpoint to the Internet or other untrusted network users.

Mitigation
Avoid storing passwords in easily accessible locations.
Mitigation
Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
Mitigation
A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.
