  • GHSA-wjfq-88q2-r34jUnhandled exception when decoding form response JSON2022-01-21ghsa · osvUS

    ### Impact When handling form responses from the client (`ModalFormResponsePacket`), the Minecraft Windows client may send weird JSON that `json_decode()` can't understand. A workaround for this is implemented in `InGamePacketHandler::stupid_json_decode()`. An `InvalidArgumentException` is thrown by this function when it fails to fix an error found in the JSON, which is not caught by the caller. This leads to a server crash. ### Patches 56fe71d939c38fe14e18a31a673a9331bcc0e4ca ### Workarounds A plugin may handle `DataPacketReceiveEvent`, capture `ModalFormResponsePacket` and run the provided JSON through `stupid_json_decode`. Note that this requires copying the body of the function to a plugin, since the function is currently private. ### For more information If you have any questions or comments about this advisory: * Email us at [team@pmmp.io](mailto:team@pmmp.io)
