Created nodejs-mixin-deep tracking bugs for this issue:

Affects: fedora-all [bug 1795476]

Comment 2 Jason Shepherd 2020-01-29 02:07:27 UTC
While OpenShift Container Platform (OCP) contains the affected nodejs-mixin-deep code, it's added as a dependency of Kibana 5. Similar issue about prototype pollution [1] have been fixed, but no known attack vector was found, so we're rating this issue as Low for OCP.

Red Hat Quay 3.2 uses nodejs-deep-mixin 1.3.2 which has a fix for this vulnerability.

Comment 11 Cedric Buissart 2020-02-25 09:10:31 UTC

In Red Hat Software Collections and Red Hat Enterprise Linux 8, nodejs-mixin-deep is bundled into nodejs-nodemon, and is not meant to be accessed outside of that package. Within nodemon, this flaw is rated with a Low severity.
