Overview

ssddanbrown/bookstack is a BookStack documentation platform

Affected versions of this package are vulnerable to Remote Code Execution (RCE). A user could upload PHP files through image upload functions, which would allow them to execute code on the host system remotely. They would then have the permissions of the PHP process. This most impacts scenarios where non-trusted users are given permission to upload images in any area of the application.
