From the errata at https://errata.devel.redhat.com/errata/container/36207#tags

You can see that the current 7.1 GA candidate image fuse-eap-openshift-container-1.1-4 is C grade

Health index now: C
The following known vulnerabilities exist for packages in this container:
Important CVE-2018-10897 RHSA-2018:2285
Important CVE-2018-12020 RHSA-2018:2181
Moderate CVE-2016-2183 RHSA-2018:2123
Moderate CVE-2018-2952 RHSA-2018:2242

The last fresh maker build https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=734797 has a grade of A so maybe we just need to use the latest jboss-eap-7-eap71-openshift-container parent like that one?
