Description Guilherme de Almeida Suckevicz 2020-07-13 13:31:17 UTC 
Incorrect handling of Upgrade header with the value websocket leads in crashing of containers hosting sockjs apps. This affects the package sockjs before 0.3.20.

Comment 3 Mark Cooper 2020-07-15 01:43:11 UTC 
In OpenShift 4 the container openshift/ose-prometheus packages a vulnerable version of npm-sockjs (0.3.19). 

It is present in the Prometheus ReactUI which is unused in OpenShift, but can still be manually accessed via the URL.

Mitigation:

There is no mitigation for this issue, the flaw can only be resolved by applying updates.
