+  * Reference new symbols.
+  * CVE-2021-22876: curl is vulnerable to an "Exposure of Private Personal
+    Information to an Unauthorized Actor" by leaking credentials in the
+    HTTP Referer: header. libcurl does not strip off user credentials from
+    the URL when automatically populating the Referer: HTTP request header
+    field in outgoing HTTP requests, and therefore risks leaking sensitive
+    data to the server that is the target of the second HTTP request.
