Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.
