    CVE-2026-86198

    PocketMine-MP versions before 5.44.2 fail to properly validate multiple ResourcePackClientResponsePacket packets with STATUS_COMPLETED status during resource pack handling. Malicious clients can send batches of these packets to repeatedly trigger pre-spawn progression, creating duplicate Player objects and amplifying memory consumption and network traffic.
