CVE-2022-2880

Requests forwarded by ReverseProxy include the raw query parameters from
the inbound request, including unparsable parameters rejected by net/http.
This could permit query parameter smuggling when a Go proxy forwards a
parameter with an unparsable value. After fix, ReverseProxy sanitizes the
query parameters in the forwarded query when the outbound request’s Form
field is set after the ReverseProxy. Director function returns, indicating
that the proxy has parsed the query parameters. Proxies which do not parse
query parameters continue to forward the original query parameters
unchanged.
