CVE-2026-86198
Mở trang đầy đủCVSS — LOW
PocketMine-MP has potential memory/network vulnerability from repeated ResourcePackClientResponsePacket packets
Mô tả
Summary
During the resource pack stage of logging in, after the server sends ResourcePackStackPacket, a malicious client can send a batch of multiple ResourcePackClientResponsePacket packets with status ResourcePackClientResponsePacket::STATUS_COMPLETED causing the server to repeatedly execute pre-spawn progression.
Impact
Multiple Player objects can be created for just a single session, increasing memory usage and amplifying outbound network traffic from duplication of large pre-spawn packets such as AvailableCommandsPacket and CreativeContentPacket.
Workarounds
Plugins can use their own PacketHandler classes that reject/ignore any extra ResourcePackClientResponsePacket packets.
