Critical (9.8). EPSS 4.0% chance of exploitation in the next 30 days. Fixed in twisted 20.3.0, 20.3.0rc1.
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.
