|---|---|---|---|---|---|---|
| CVE-2024-3935 | In Eclipse Mosquito, versions from 2.0.0 through 2.0.18, if a Mosquitto broker is configured to create an outgoing bridge connection, and that bridge connection has an incoming topic configured that makes use of topic remapping, then if the remote connection sends a crafted PUBLISH packet to the broker a double free will occur with a subsequent crash of the broker. | [email protected] | 6.0 | 0.76% | 2024-10-30 | 2025-11-03 |

| CVE-2024-8376 | In Eclipse Mosquitto up to version 2.0.18a, an attacker can achieve memory leaking, segmentation fault or heap-use-after-free by sending specific sequences of "CONNECT", "DISCONNECT", "SUBSCRIBE", "UNSUBSCRIBE" and "PUBLISH" packets. | [email protected] | 7.2 | 0.75% | 2024-10-11 | 2024-11-15 |
| CVE-2023-5632 | In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption.

This occurs because of mishandling of EAGAIN from the libc send function. | [email protected] | 7.5 | 1.11% | 2023-09-01 | 2025-06-26 |
| CVE-2021-41039 | In versions 1.6 to 2.0.11 of Eclipse Mosquitto, an MQTT v5 client connecting with a large number of user-property properties could cause excessive CPU usage, leading to a loss of performance and possible denial of service. | [email protected] | 7.5 | 1.26% | 2021-12-01 | 2024-11-21 |
| CVE-2021-34434 | In Eclipse Mosquitto versions 2.0 to 2.0.11, when using the dynamic security plugin, if the ability for a client to make subscriptions on a topic is revoked when a durable client is offline, then existing subscriptions for that client are not revoked. | [email protected] | 5.3 | 1.27% | 2021-08-30 | 2024-11-21 |

| CVE-2021-34431 | 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. | [email protected] | 6.5 | 1.11% | 2021-07-22 | 2024-11-21 |
| CVE-2021-28166 | 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. | [email protected] | 6.5 | 0.97% | 2021-04-07 | 2024-11-21 |
| CVE-2019-11779 | In Eclipse Mosquitto 1.5.0 to 1.6.5 inclusive, if a malicious MQTT client sends a SUBSCRIBE packet containing a topic that consists of approximately 65400 or more '/' characters, i.e. the topic hierarchy separator, then a stack overflow will occur. | [email protected] | 6.5 | 2.74% | 2019-09-19 | 2024-11-21 |
| CVE-2019-11778 | 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. | [email protected] | 5.4 | 0.76% | 2019-09-18 | 2024-11-21 |

| CVE-2018-12551 | When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use a password file for authentication, any malformed data in the password file will be treated as valid. This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who hav | [email protected] | 8.1 | 1.47% | 2019-03-27 | 2024-11-21 |
| CVE-2018-12550 | When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use an ACL file, and that ACL file is empty, or contains only comments or blank lines, then Mosquitto will treat this as though no ACL file has been defined and use a default allow policy. The new behaviour is to have an empty ACL file mean that all access is denied, which is not a useful configuration but is not unexpected. | [email protected] | 8.1 | 1.35% | 2019-03-27 | 2024-11-21 |
| CVE-2018-12546 | 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. | [email protected] | 6.5 | 0.82% | 2019-03-27 | 2024-11-21 |
| CVE-2018-20145 | Eclipse Mosquitto 1.5.x before 1.5.5 allows ACL bypass: if the option per_listener_settings was set to true, and the default listener was in use, and the default listener specified an acl_file, then the acl file was being ignored. | [email protected] | 7.5 | 1.65% | 2018-12-13 | 2024-11-21 |
| CVE-2018-12543 | In Eclipse Mosquitto versions 1.5 to 1.5.2 inclusive, if a message is published to Mosquitto that has a topic starting with $, but that is not $SYS, e.g. $test/test, then an assert is triggered that should otherwise not be reachable and Mosquitto will exit. | [email protected] | 7.5 | 36.01% | 2018-11-15 | 2024-11-21 |
