CVE-2025-62723 Medium · 4.3 CWE-772 Oct 24, 2025
FlashMQ does not release memory of queued QoS messages
FlashMQ is a MQTT broker/server, designed for multi-CPU environments. Prior to version 1.23.2, any authenticated user can create sessions and have them collect QoS messages. When not sent to a client, these are then not released upon (eventual) session expiration. Version 1.23.2 fixes the issue.
