NVD Description

Note: Versions mentioned in the description apply only to the upstream nats-server-oci-compat package and not the nats-server-oci-compat 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, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, when no_auth_user was configured, a parser fast path intended for ordinary client connections could also apply to route or leafnode listeners, allowing an unauthenticated peer to bypass inter-server CONNECT authentication and operate with the privileges associated with that connection type. This issue is fixed in versions 2.14.0, 2.12.7, and 2.11.16.
