What is CVE-2022-2880?
CVE-2022-2880 is a high-severity vulnerability in Golang Go, published on 14 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
