  - A Teacher creating a Calculated question can intentionally cause remote code execution on the server, aka eval injection.

  - Students who submitted assignments and exported them to portfolios can download any stored Moodle file
    by changing the download URL.

  - Students who posted on forums and exported the posts to portfolios can download any stored Moodle file
    by changing the download URL.

  - An authenticated user is allowed to add HTML blocks containing scripts to their Dashboard.
    This is normally not a security issue because a personal dashboard is visible to this user only.
    Through this security vulnerability,
    users can move such a block to other pages where they can be viewed by other users.

  - By substituting URLs in portfolios, users can instantiate any class.
    This can also be exploited by users who are logged in as guests to create a DDoS attack.");
