PocketMine-MP before 4.2.10 Denial of Service via Chat Messages

PocketMine-MP before 4.2.10 fails to validate the total length of incoming chat message blobs before splitting them by newline characters, allowing attackers to send large messages containing many newlines. Malicious clients can send megabyte-sized chat packets and bombard the server with thousands of such messages, causing server lockups lasting seconds or minutes.

PocketMine-MP before 3.18.1 Denial of Service via MovePlayerPacket

PocketMine-MP versions before 3.18.1 fail to validate NaN or INF values in MovePlayerPacket position and rotation fields.

CVE-2021-48006 Baixa · 3.3 CWE-178 06/09/2026

PocketMine-MP before 4.0.3 Operator Privilege Escalation via Case Sensitivity

PocketMine-MP before 4.0.3 does not perform case-insensitive matching when removing operator entries from ops.txt. The removeOp function lowercases the supplied name but only removes an exactly matching entry, so an operator name stored with non-lowercase letters cannot be revoked using the deop command, leaving the player as an operator until the entry is removed from ops.txt manually.

CVE-2020-37277 Média · 6.5 CWE-400 06/09/2026

PocketMine-MP before 3.15.4 Denial of Service via InventoryTransaction

PocketMine-MP versions before 3.15.4 contain a denial of service vulnerability in the InventoryTransaction component's findResultItem() method. Malicious clients can send specially crafted InventoryTransactionPackets with multiple conflicting pathways to cause exponential processing complexity, freezing the server.
