CVE-2023-7332: PocketMine-MP < 4.18.1 Improper Validation of Dropped Item Count Allows Remote Server Crash
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.
Security readout for executives and security teams
Plain-English summary
A player who can join a vulnerable PocketMine-MP server could send an invalid item-drop request that crashes the server. The business impact is service outage for Minecraft Bedrock servers, not data theft or code execution based on the provided sources.
Executive priority
Treat as high priority for public PocketMine-MP services because a valid player can cause downtime. It is less urgent for isolated or already upgraded servers.
Technical view
CVE-2023-7332 is improper input validation in PocketMine-MP inventory transaction handling before 4.18.1. A remote authenticated player can request dropping more items than exist in the hotbar, triggering denial of service. CVSS 4.0 is 7.1 with high vulnerable-system availability impact.
Likely exposure
Exposure is limited to PocketMine-MP servers running versions earlier than 4.18.1 and accepting valid player sessions from potentially untrusted users.
Exploitation context
The bundle does not show CISA KEV listing or confirmed active exploitation. Exploitation requires network access and low privileges through a valid player session, with no user interaction.
Researcher notes
Sources describe a crash-only availability flaw in dropped-item count validation. Do not infer code execution, data exposure, or active exploitation from the provided evidence.
Mitigation direction
Upgrade PocketMine-MP to 4.18.1 or later.
Review the GitHub advisory and release notes for vendor guidance.
Identify internet-facing or public player-accessible PocketMine-MP servers.
Prioritize servers used for public communities or revenue-generating gameplay.
Validation and detection
Check deployed PocketMine-MP versions for releases earlier than 4.18.1.
Confirm patched servers include the vendor fix commit or newer release.
Review logs for crashes tied to inventory transaction or item drop handling.
Verify player access controls for public or semi-public servers.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Validation of Specified Quantity in Input
Improper Validation of Specified Quantity in Input represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
