Comment 5 Mark Cooper 2020-03-19 04:37:19 UTC 
ServiceMesh packages sockjs in the following components:
 - servicemesh-grafana
 - jaeger
 - kiali 

However, all components use at least 0.3.18+ and are not vulnerable to the XSS flaw.
Comment 6 Mark Cooper 2020-03-19 04:40:28 UTC 
Jaeger v1.17.0 is also not vulnerable, packaging v0.3.19 of sockjs.
