WS-2023-0003
Date: August 19, 2025
PocketMine-MP prior to 4.12.5 vulnerable to denial-of-service by sending large modal form responses. Due to a workaround for an old client bug (which has since been fixed), very large JSON payloads in ModalFormResponsePacket were able to cause the server to spend a significant amount of time processing the packet. Large numbers of these packets were able to hog CPU time so as to prevent the server from processing other connections in a timely manner.
