+  * CVE-2020-10108: 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.
+  * CVE-2020-10109: 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.
+  * CVE-2022-21712: twisted exposes cookies and authorization headers when
+    following cross-origin redirects. This issue is present in the
+    `twisted.web.RedirectAgent` and `twisted.web.BrowserLikeRedirectAgent`
+    functions.
