Doc Type: If docs needed, set a value
Doc Text:
It was found that when a Node.js script is run in inspector mode, Node.js did not properly validate the Host header, leaving the inspector vulnerable to a DNS rebind attack and bypass same-origin policy. If a developer had an inspector session running, and was visiting a malicious website, the site could carry on a DNS rebind attack, allowing the site to have full access to the debugged script.

Description Adam Mariš 2018-03-29 09:50:14 UTC 
A malicious website could use a DNS rebinding attack to trick a web browser to bypass same-origin-policy checks and allow HTTP connections to localhost or to hosts on the local network, potentially to an open inspector port as a debugger, therefore gaining full code execution access.

Comment 1 Adam Mariš 2018-03-29 12:08:15 UTC 
Created nodejs tracking bugs for this issue:

Affects: fedora-all [bug 1562027]
Affects: epel-all [bug 1562026]
Comment 7 Cedric Buissart 2018-04-05 11:52:43 UTC 
rh-nodejs4-nodejs is not affected since NodeJS 4 has no support for the inspector.
Comment 12 Jason Shepherd 2018-06-13 21:19:33 UTC 
NodeJS is only packaged as an ImageStream in Openshift Enterprise 3.9, which is a container image from RH Software Collections. Marking Openshift Enterprise as not affected.
