Overview
Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime due to the improper release of memory for queued QoS messages in authenticated user sessions. An attacker can cause increased memory consumption and potential denial of service by creating sessions that accumulate unsent QoS messages, which are not released even after session expiration.
