CVE-2026-73863 NanoMQ: Heap-Buffer-Overflow in `nmq_subinfo_decode()` During MQTT v5 SUBSCRIBE Parsing

NanoMQ is an MQTT broker. Prior to 0.24.14, NanoMQ's broker-side MQTT v5 nmqsubinfodecode function in nng/src/sp/protocol/mqtt/mqttparser.c reuses lenofvarint from the outer Properties Length while parsing each SUBSCRIPTIONIDENTIFIER. A remote client can send a SUBSCRIBE packet with a multi-byte...

CVE-2026-73863

NanoMQ, an MQTT broker, contains a heap-buffer-overflow in the broker-side function nmq_subinfo_decode() located in nng/src/sp/protocol/mqtt/mqtt_parser.c. The root cause is an incorrect reuse of the len_of_varint value from the outer Properties Length field when parsing repeated SUBSCRIPTION_IDE...

CVE-2026-44639 NanoMQ: O(N²) Denial of Service in MQTT v5 Property Parsing

NanoMQ is an MQTT broker. Prior to 0.24.14, NanoMQ's MQTT v5 property decoder in nng/src/supplemental/mqtt/mqttcodec.c uses propertyappend to walk the entire linked list for each property added by decodebufproperties. A remote unauthenticated client can supply a PUBLISH or SUBSCRIBE packet...

CVE-2026-44639

NanoMQ , an MQTT broker, is vulnerable to an O(N²) denial of service in its MQTT v5 property decoder (in nng/src/supplemental/mqtt/mqtt_codec.c). The root cause is that property_append() traverses the entire linked list for each property added by decode_buf_properties(), resulting in quadratic CP...
