Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the properties_parse process when a POST request is sent to /api/v4/mqtt/publish with user_properties formatted as a JSON array instead of a JSON object. An attacker can cause the broker process to crash by submitting malformed data that triggers a NULL pointer dereference.
