Affected: Bitnami: nats

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, the NATS message header `Nats-Request-Info:` is supposed to be a guarantee of identity by the NATS server, but the stripping of this header from inbound messages was not fully effective. An attacker with valid credentials for any regular client interface could thus spoof their identity to services which rely upon this header. Versions 2.11.15 and 2.12.6 contain a fix. No known workarounds are available.

Affected: Go: github.com/nats-io/nats-server/v2, Go: github.com/nats-io/nats-server

### Background

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 offers a `Nats-Request-Info:` message header, providing information about a request.

### Problem Description

The NATS message header `Nats-Request-Info:` is supposed to be a guarantee of identity by the NATS server, but the stripping of this header from inbound messages was not fully effective.

An attacker with valid credentials for any regular client interface could thus spoof their identity to services which rely upon this header.

### Affected Versions

Any version before v2.12.6 or v2.11.15

### Workarounds

None.
