# CVE-2023-7332: PocketMine-MP < 4.18.1 Improper Validation of Dropped Item Count Allows Remote Server Crash

Status: published. Published: 2025-12-31. Updated: 2026-11-08.

PocketMine-MP versions prior to 4.18.1 contain an improper input validation vulnerability in inventory transaction handling. A remote attacker with a valid player session can request that the server drop more items than are available in the player's hotbar, triggering a server crash and resulting in denial of service.
