NVD Description

Note: Versions mentioned in the description apply only to the upstream nats-server package and not the nats-server 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 2.14.3 and 2.12.12, MQTT retained message delivery and QoS1+ durable replay could deliver messages whose original topics matched a subscriber configured subscribe deny rule because these delivery paths did not consistently recheck the concrete original topic before sending the MQTT PUBLISH to the subscriber. This issue is fixed in versions 2.14.3 and 2.12.12.
