Overview

Mosquitto is an open source implementation of a server for version 3.1 and 3.1.1 of the MQTT protocol.

Affected versions of this package are vulnerable to Improper Authorization. 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.
