kubernetes – Kubenetes pod passwd

I have a simple Angular application and I deployed it on an Nginx server in a POD on a Kubernetes environment. I realised that I am now able to access the /etc/passwd file on the POD, without even having to login into the POD. Since this is the /etc/passwd file for a POD, should I be concerned?

A sample command that I tried is

curl http://test_k8s_route/?../../../../../../../../../../../etc/passwd
