Description
The vulnerability allows logged in back end users to view records that have not been enabled for them. There are two ways to exploit the vulnerability:
1. If a back end user without page mounts uses the filter menu in the site structure, they will see all pages matching the filter, even though they have not been enabled for them.
2. Through URL manipulation, a back end user can access records in parent view, which have not been enabled for them – e.g. articles of another user or news items of another archive. It is not possible to alter these records though.
