How to fix?

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

NVD Description

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

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.
