Overview
Affected versions of this package are vulnerable to Missing Authorization via the /api/site/find route. An attacker can access sensitive page information, including full content and metadata, by sending requests with known or guessed page IDs or UUIDs as an authenticated user. This is only exploitable if the user's role does not have the pages.access permission configured in the user blueprint, model blueprint options, or both.
