Description Michael Kaplan 2021-04-30 14:38:34 UTC 
The package browserslist from 4.0.0 and before 4.16.5 are vulnerable to Regular Expression Denial of Service (ReDoS) during parsing of queries.
Comment 3 Przemyslaw Roguski 2021-05-07 16:10:28 UTC 
Statement:

While some components do package a vulnerable version of nodejs browserslist library, access to them requires OpenShift OAuth credentials and hence have been marked with a Low impact. 
This applies to the following products:
  - OpenShift Container Platform (OCP)
  - OpenShift ServiceMesh (OSSM)

In Red Had Quay , whilst a vulnerable version of `browserslist` is included in the quay-rhel8 container it is a development dependency only, therefor the impact is low.
