CVE-2021-22876
Description
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.
