| CVE-2021-34431 | 1 Eclipse | 1 Mosquitto | 2021-08-03 | 4.0 MEDIUM | 6.5 MEDIUM |
| In Eclipse Mosquitto version 1.6 to 2.0.10, if an authenticated client that had connected with MQTT v5 sent a crafted CONNECT message to the broker a memory leak would occur, which could be used to provide a DoS attack against the broker. | |||||
| CVE-2021-28166 | 1 Eclipse | 1 Mosquitto | 2021-04-13 | 4.0 MEDIUM | 6.5 MEDIUM |
| In Eclipse Mosquitto version 2.0.0 to 2.0.9, if an authenticated client that had connected with MQTT v5 sent a crafted CONNACK message to the broker, a NULL pointer dereference would occur. | |||||
| CVE-2018-12546 | 1 Eclipse | 1 Mosquitto | 2020-08-28 | 4.0 MEDIUM | 6.5 MEDIUM |
| In Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) when a client publishes a retained message to a topic, then has its access to that topic revoked, the retained message will still be published to clients that subscribe to that topic in the future. In some applications this may result in clients being able cause effects that would otherwise not be allowed. | |||||
| CVE-2019-11778 | 1 Eclipse | 1 Mosquitto | 2019-10-09 | 5.5 MEDIUM | 5.4 MEDIUM |
| If an MQTT v5 client connects to Eclipse Mosquitto versions 1.6.0 to 1.6.4 inclusive, sets a last will and testament, sets a will delay interval, sets a session expiry interval, and the will delay interval is set longer than the session expiry interval, then a use after free error occurs, which has the potential to cause a crash in some situations. | |||||
| CVE-2017-7650 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2019-10-03 | 4.0 MEDIUM | 6.5 MEDIUM |
| In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto. | |||||

| The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients. | |||||
| CVE-2017-9868 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2019-03-12 | 2.1 LOW | 5.5 MEDIUM |
