Overview
Affected versions of this package are vulnerable to Missing Authorization via the backend logic for the pages picker process. An attacker can confirm the existence of arbitrary pages and retrieve the value of the title field by providing the full path to an existing page as an authenticated user. This is only exploitable if the pages.access permission is disabled for the user's role in the relevant blueprint configuration.
