CVE-2026-47275 nanomq NULL Pointer Dereference in MQTTv5 Client CONNECT Decoder Leading to Remote DoS
In nanomq versions 0.24.11 and earlier, a NULL pointer dereference in nnimqttv5msgdecodeconnect allows a malicious MQTT broker to crash any connecting NanoMQ MQTTv5 client including bridge mode with a single packet, causing remote denial of service via SIGSEGV. In nnimqttv5msgdecodeconnect...
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 ...
