CVE-2026-60065
When NGINX Plus is configured to use the Message Queuing Telemetry Transport MQTT filter module ngxstreammqttfiltermodule, unauthenticated attackers can send requests with conditions beyond the attacker's control to cause a heap buffer over-read in the NGINX worker process, leading to a restart...
CVE-2026-60065
CVE-2026-60065 affects NGINX Plus when the MQTT filter module (ngx_stream_mqtt_filter_module) is enabled. Unauthenticated attackers can send crafted requests to trigger a heap buffer over-read in an NGINX worker process, potentially causing a restart. Impact is limited to data-plane availability ...

CVE-2026-58210
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, an unauthenticated MQTT client could cause the server to retain large incomplete MQTT CONNECT packets before authentication completed, consuming server memory while the...
CVE-2026-58214
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, an authenticated MQTT client could subscribe to the internal $MQTT.deliver.pubrel subject family, bypassing configured subscribe permissions and exposing MQTT QoS2 protoc...
CVE-2026-58213
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.1 and 2.12.9, an MQTT client could include protocol control characters in subscription filters that were later forwarded as NATS protocol data to route or leafnode connections, corrupti...

Name of the Vulnerable Software and Affected Versions NATS Server versions prior to 2.14.3 NATS Server versions prior to 2.12.12 Description MQTT retained message delivery and QoS1+ durable replay may deliver messages to subscribers even if the original topics match a configured subscribe deny...
Security Analysis of a Communication Protocol: MQTT
This paper analyzes the security of the Message Queuing Telemetry Transport MQTT protocol in the context of the Internet of Things IoT. The main objective consists of identifying vulnerabilities and proposing security improvements. Adopting a hybrid methodology, a theoretical review was combined...
DEBIAN-CVE-2026-44248
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader method is called before the...
Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of size limits applied to the Properties section during the decoding process. An attacker can cause excessive CPU and memory consumption by sending MQTT messages with...

GHSA-C825-6PH3-4H84 Apache ActiveMQ is Vulnerable to Integer Overflow or Wraparound
Apache ActiveMQ does not properly validate the remaining length field which may lead to an overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT...
CVE-2026-22535
CVE-2026-22535 concerns an attacker with network access and valid credentials who can write to the server topics that control MQTT communications due to unencrypted MQTT protocol. The issue is described across multiple feeds (Red Hat, NVD, CIRCL, CVE lists, EUVD/ENISA, CNNVD, etc.) as a vulnerabi...
Man-In-The-Middle (MITM) Attack
MQTT is vulnerable to a Man-in-the-Middle MITM attack. The vulnerability is due to missing hostname verification by default, which allows an attacker to intercept and manipulate communication between clients and servers...
