curl 7.1.1 to and including 7.75.0 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.
