testing vulneabilities with trivy: are there a lot?!?!

[posta246]

Hi people,
post here as suggested in the issues area.
Just tested a fresh new installation (2.9.13) with this
https://aquasecurity.github.io/trivy/v0.22.0/
with the following command
docker run --rm -v /test:/root/.cache/ aquasec/trivy:0.22.0 jc21/nginx-proxy-manager
and I obtain a lot vulnerabilities, is it normal?
Sorry me if I misunderstand the use of the tool!
Thanks to all!
