Created nodejs tracking bugs for this issue: Affects: epel-all [bug 1661007] Affects: fedora-all [bug 1661006]
Quick correction on nodejs 6 : the commit 5d9005c35 is also required. The fixed version is actually 6.15.1

Statement: The nodejs RPMs shipped in Red Hat OpenShift Container Platform (OCP) versions 3.6 through 3.10 are vulnerable to this flaw because they contain the affected code. Later versions of OCP used nodejs RPMs delivered from Red Hat Software Collections and Red Hat Enterprise Linux channels.
Mitigation: The use of a Load Balancer or a Reverse Proxy will increase the difficulty of the attack.
This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.4 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.5 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.6 EUS Via RHSA-2019:1821 https://access.redhat.com/errata/RHSA-2019:1821
