An access control issue in NanoMQ v0.21.10 allows attackers to bypass security restrictions and access sensitive system topic messages using MQTT wildcard characters.

NanoMQ 0.17.5 has a one-byte heap-based buffer over-read in the conn_handler function of mqtt_parser.c when it processes malformed messages.

In Meari IoT Cloud MQTT Broker deployments running EMQX 4.x, any authenticated low-privilege account can subscribe to global wildcard topics and receive telemetry from devices the user does not own. The broker enforces publish restrictions but does not enforce equivalent…

NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. MQTT v5 Variable Byte Integer parsing out-of-bounds: get_var_integer() accepts 5-byte varints without bounds checks; reliably triggers OOB read / crash when built with ASan. This affects 0.24.6 and earlier.

NanoMQ v0.22.7 is vulnerable to Denial of Service (DoS) due to improper resource throttling. A crafted sequence of requests causes the recv-q queue to saturate, leading to the rapid exhaustion of system file descriptors (FDs). This exhaustion triggers a process crash, rendering…

NanoMQ MQTT Broker (NanoMQ) is an Edge Messaging Platform. Prior to version 0.24.2, there is a classical data racing issue about sub info list which could result in heap use after free crash. This issue has been patched in version 0.24.2.

NanoMQ v0.17.9 was discovered to contain a heap use-after-free vulnerability via the component sub_Ctx_handle. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted SUBSCRIBE message.

A segmentation fault in NanoMQ v0.21.10 allows attackers to cause a Denial of Service (DoS) via crafted messages.

An invalid read size in Nanomq v0.21.9 allows attackers to cause a Denial of Service (DoS).

Null Pointer Dereference vulnerability in topic_filtern function in mqtt_parser.c in NanoMQ 0.21.7 allows attackers to cause a denial of service.

NanoMQ 0.16.5 is vulnerable to heap-use-after-free in the nano_ctx_send function of nmq_mqtt.c.

In NanoMQ v0.15.0-0, segment fault with Null Pointer Dereference occurs in the process of decoding subinfo_decode and unsubinfo_decode.

In NanoMQ v0.15.0-0, a Heap overflow occurs in copyn_utf8_str function of mqtt_parser.c

In NanoMQ v0.15.0-0, Heap overflow occurs in read_byte function of mqtt_code.c.

EMQ X Broker versions prior to 4.2.8 are vulnerable to a denial of service attack as a result of excessive memory consumption due to the handling of untrusted inputs. These inputs cause the message broker to consume large amounts of memory, resulting in the application being…

A heap-buffer-overflow vulnerability in the read_byte function in NanoMQ v.0.21.7 allows attackers to cause a denial of service via transmission of crafted hexstreams.

NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Versions prior to 0.24.11 have a remotely triggerable heap buffer overflow in the `uri_param_parse` function of NanoMQ's REST API. The vulnerability occurs due to an off-by-one error when allocating memory for…

NanoMQ v0.22.10 was discovered to contain a memory leak which allows attackers to cause a Denial of Service (DoS) via a crafted PUBLISH message.

NanoMQ v0.22.10 was discovered to contain a heap overflow which allows attackers to cause a Denial of Service (DoS) via a crafted CONNECT message.

nanomq 0.21.2 contains a Use-After-Free vulnerability in /nanomq/nng/src/core/socket.c.
