There are many apps on marketplace, let's say about JIRA product.
If I install an app, assuming no further access requests is given (not sure there is actually), what can this app know (inquiry) and do (change) about my site or product?
Then a user starts to use the app, does the app have the same rights as the user currently using it, or higher?
In a simple question, what is the maximum security exposure I risk when installing an app?
thanks!
