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, users with JetStream admin API access to restore one stream could restore to other stream names, impacting data which should have been protected against them. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, if developers have configured users to have limited JetStream restore permissions, temporarily remove those permissions.
