medium Tenable Self-Hosted Container Security Plugin ID 478561

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)
