NVD Description

Note: Versions mentioned in the description apply only to the upstream nats-server-fips package and not the nats-server-fips package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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, when using ACLs on message subjects, these ACLs were not applied in the $MQTT.&gt; namespace, allowing MQTT clients to bypass ACL checks for MQTT subjects. Versions 2.11.15 and 2.12.6 contain a fix. No known workarounds are available.
