GHSA-pqp3-8rrw-g8vm: PocketMine-MP vulnerable to server crash with certain invalid JSON payloads in `LoginPacket` due to vulnerable dependency
(updated )
An attacker could crash PocketMine-MP by sending malformed JSON in LoginPacket.
This happened due to a bug in netresearch/jsonmapper. The library wasn’t doing proper checks when mapping JSON arrays and objects onto scalar model properties such as strings.
