Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions 4.0.0 up to but not including 4.0.7 of the PocketMine-MP server package (pocketmine/pocketmine-mp) are affected. When a Minecraft Windows client sends malformed form response JSON, an InvalidArgumentException thrown by the JSON workaround function is not caught, which crashes the server; the source does not state whether any special access is needed to trigger it. Upgrade to version 4.0.7, which is listed as the fixed version.
