No. nginx remote exploits are extremely few and far between. Hosting a static site made out of html pages and actual files in directories is incredibly low risk and requires no maintainance or particular security knowledge. If all you need is a simple webserver it's best to host it yourself. If you need anything more you're better off letting someone else host it.
