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

  - REST client for Ruby (aka rest-client) before 1.8.0 allows remote attackers to conduct session fixation
    attacks or obtain sensitive cookie information by leveraging passage of cookies set in a response to a
    redirect. (CVE-2015-1820)

Andy Brody reports :

When Ruby rest-client processes an HTTP redirection response, it blindly passes along the values from any Set-Cookie headers to the redirection target, regardless of domain, path, or expiration.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1313 advisory.
