CVSS 5.300000190734863 MEDIUM
A flaw was found in tornado-python. A remote attacker can exploit this vulnerability by sending a specially crafted, very large multipart body with numerous parts. Because the parsing of these large bodies occurs synchronously on the main thread, it can consume excessive resources, leading to a denial of service (DoS) for the application.
