Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the MQTT-over-WebSocket transport when processing packets with a large Remaining Length value in the fixed header and a shorter actual payload. An attacker can cause a crash by sending specially crafted MQTT packets that trigger an out-of-bounds read.
