0 NATS Server versions prior to 2.14.3 and 2.12.12 contain a vulnerability where MQTT retained message delivery and QoS1+ durable replay can bypass subscribe deny filters. This occurs because these delivery paths do not consistently recheck the original topic against deny rules before sending messages to subscribers. The issue allows delivery of messages that should have been blocked by subscription deny rules. A fix is available in versions 2.14.3 and 2.12.12.

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, a client could be registered as the configured no_auth_user through a parser path used when the first client operation was not CONNECT, bypassing user-level connection restrictions such as allowed_connection_types or proxy_required that normal authentication would apply. This issue is fixed in versions 2.14.3 and 2.12.12. Join the discussion | CVE Database V5 | 07/08/2026, 20:16:25 UTC Added: 07/08/2026, 20:44:01 UTC |
