Description (CNA)
PocketMine-MP versions before 5.39.2 fail to validate entity despawn state when processing attack packets from clients. Attackers can exploit a race condition by attacking a disconnecting player to trigger multiple death handlers, causing inventory items and experience to drop multiple times for duplication.
