An attacker may bypass validation checks and retrieve\ncredentials.\n\nCVE-2020-10108\n\n HTTP request splitting vulnerability. When presented with two\n content-length headers, it ignored the first header. When the\n second content-length value was set to zero, the request body was\n interpreted as a pipelined request.\n\nCVE-2020-10109\n\n HTTP request splitting vulnerability. When presented with a\n content-length and a chunked encoding header, the content-length\n took precedence and the remainder of the request body was\n interpreted as a pipelined request.\n\nCVE-2022-21712\n\n Twisted exposes cookies and authorization headers when following\n cross-origin redirects.
