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 supports telemetry on messages, using the per-message NATS headers.
A valid client which uses message tracing headers can indicate that the trace messages can be sent to an arbitrary valid subject, including those to which the client does not have publish permission.
The payload is a valid trace message and not chosen by the attacker.
Any version before v2.12.6 or v2.11.15
None.
