CRITICAL 9.8EPSS 3.97%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.97%). 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 two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.
