Vulnerability Title
Undertow: undertow: denial of service due to premature multipart/form-data parsing in get requests
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentially resulting in a Denial of Service (DoS).
