Vulnerability Insight:
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)
A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. The highest threat from this vulnerability is to confidentiality.(CVE-2021-22924)
A has been found in curl. The fix for CVE-2021-22898 doesn't remedy the vulnerability.
