Authenticated server crash via unchecked inventory slot
Published Sep 9, 2026 · Updated Sep 9, 2026
Improper input validation in PMMP PocketMine-MP before 5.11.2 allows remote authenticated users to crash the server via BookEditPacket. InGamePacketHandler::handleBookEdit passes the packet's inventorySlot directly to BaseInventory::getItem without first verifying that the slot exists, so a value above 35 throws an unhandled exception. A connected client can interrupt the entire server; the advisory reports no confidentiality or integrity impact.
