NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian:11.
See How to fix? for Debian:11 relevant fixed versions and status.
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.
