## Description

StudioCMS is a server-side-rendered, Astro native, headless content management system. Versions prior to 0.2.0 contain a Broken Object Level Authorization (BOLA) vulnerability in the Content Management feature that allows users with the "Visitor" role to access draft content created by Editor/Admin/Owner users. Version 0.2.0 patches the issue.
