Description Pedro Sampaio 2018-02-16 20:56:37 UTC 
A flaw was discovered in is-myjson-valid before 1.4.1 and 2.17.2. Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks. It used a regular expression (/^\S+@\S+$/) in order to validate emails. This can cause an impact of about 10 seconds matching time for data 90K characters long.

Comment 4 Jason Shepherd 2018-06-13 21:29:49 UTC 
NodeJS is shipped in Openshift Enterprise 3.9 as ImageStreams. Those ImageStreams are the RH Software Collection images. Setting Openshift Enterprise 3 as not affected.
Comment 9 Jason Shepherd 2021-05-07 01:38:18 UTC 
Statement:

In Red Hat Quay the is-my-json-valid library is included as a build time dependency of protractor. It's only used at build time, not at runtime reducing the impact to low.
