Does app store app stores data in the private/var/mobile/containers/data/application

I have an security issue reported with iOS app created using the Enterprise certificate;
that API service response is getting stored in the private/var/mobile/containers/data/application which has certain important client information

Can this be issue of response getting stored in the private/var/mobile/containers/data/application in the appstore app ???
If yes then what would be the recommendation to fix this

DATA BEING STORED IN THE container folder :
