There is no fixed version for RHEL:7 rubygem-excon.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygem-excon package and not the rubygem-excon package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Excon is usable, fast, simple HTTP 1.1 for Ruby. Prior to 1.5.0, Excon's RedirectFollower middleware failed to strip additional sensitive headers when following redirects and did not provide a custom list of headers to strip. This could cause inadvertent leakage of sensitive data when the initial request includes header information that is not intended for the new target. This issue is fixed in version 1.5.0.
