Not having been revealed or made visible; kept hidden or protected from view.

Unexposed → It is formed from "un-" (meaning not) and "exposed" (from Latin "exponere", meaning to put out or to expose). The word "unexposed" means not put out or not revealed.
Think of 'not' ('un-') revealing something that is 'put out' ('exponere') — that's why unexposed means something that is not revealed.
