CVE-2026-86202: Insufficient Control of Network Message Volume (Network Amplification) in pmmp PocketMine-MP
PocketMine-MP versions before 5.39.2 contain a network amplification vulnerability in ActorEventPacket handling that allows clients to trigger consuming animations for all visible players. Attackers can send crafted ActorEventPacket messages to spam animation events to other clients and waste server CPU and memory resources.
AI Analysis
Technical Summary
CVE-2026-86202 describes a network amplification vulnerability in PocketMine-MP prior to version 5.39.2. The vulnerability arises from insufficient control over the volume of network messages related to ActorEventPacket handling. Attackers can exploit this by sending specially crafted ActorEventPacket messages that cause the server to broadcast consuming animation events for all visible players, leading to resource exhaustion on the server side.
Potential Impact
Exploitation of this vulnerability can cause denial of service conditions by overwhelming the server's CPU and memory resources through amplified network message traffic. This can degrade server performance and availability for legitimate users.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch link is provided, users should monitor vendor communications for updates. Until a fix is available, consider limiting client message rates or implementing network-level controls to mitigate potential abuse.
