AI-suggested
Upgrade to Moquette version 0.18.1 or later, where this vulnerability is fixed by enforcing maximum lengths on pending per-session message queues. No other mitigation is required as the fix is official and available.
Description
Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, the broker does not enforce a maximum length for pending per-session message queues. When a fast publisher sends messages to a slow subscriber whose in-flight window is full, queued messages can accumulate without bound in memory or persistent storage. Remote clients can use this condition to exhaust broker resources and cause a denial of service. This issue is fixed in version 0.18.1.
