Description
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Hostname spoofing in URL parser for javascript protocol: If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

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.
