What is CVE-2026-3260?

A security flaw in Undertow allows remote attackers to exploit the server by sending an HTTP GET request with multipart/form-data content. When the application processes these parameters using methods such as getParameterMap(), it can lead to premature parsing and unauthorized storage of data on disk. This action can induce resource exhaustion, ultimately causing Denial of Service (DoS) situations, affecting system reliability and availability.
