When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly(CVE-2021-22890) 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(CVE-2021-22876)
