After I upgraded the elastic stack to 8.6.0 and carried out a vulnerability scan on Kibana using the microfocus tool, there were vulnerabilities as follows:

I have made changes to the Kibana configuration, namely changing

`server.securityResponseHeaders.xContentTypeOptions: "nosniff"`

but that does not solve the problem, this vulnerability is still detected in the next scan.

Please suggest me any solution to rectify this.

Hey @Septianingrum.17 !

"nosniff" is the default value for that setting.

Can you provide more info about which endpoint you're running against?
