What is CVE-2025-29784?

NamelessMC, a widely used software for managing Minecraft servers, has a vulnerability that affects version 2.1.4 and earlier. The issue arises from insufficient length validation for the 's' parameter in GET requests related to forum search functionality. This oversight enables attackers to input excessively long search queries, potentially leading to significant performance degradation and denial-of-service conditions. The vulnerability has been addressed in version 2.2.0, where proper validation controls have been implemented to mitigate this risk.
