Vulnerability from cvelistv5 – Published: 2026-09-09 13:31 – Updated: 2026-09-09 14:15

Title

PocketMine-MP before 5.25.2 Denial of Service via explode

Summary

PocketMine-MP versions before 5.25.2 fail to limit the explode() function in packet parsing, allowing malicious clients to waste server resources. Attackers can send crafted packets with excessive delimiters to consume CPU and memory through sign editing, JWT parsing, and command parsing endpoints.
