Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

There is a possible DoS vulnerability in the multipart parser in Rack before 2.0.6. Specially crafted requests can cause the multipart parser to enter a pathological state, causing the parser to use CPU resources disproportionate to the request size.
