The vulnerability was found Moodle which exists because the application allows a user to control path of the older to create in TinyMCE loaders. A remote user can send a specially crafted HTTP request and create arbitrary folders on the system.

If the algebra filter was enabled but not functional (eg the necessary binaries were missing from the server), it presented an XSS risk.

The Mustache pix helper contained a potential Mustache injection risk if combined with user input (note: This did not appear to be implemented/exploitable anywhere in the core Moodle LMS).

H5P metadata automatically populated the author with the user's username, which could be sensitive information.

The link to reset all templates of a database activity did not include the necessary token to prevent a CSRF risk.

In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user who also has direct access to the web server outside of the Moodle webroot could utilise a local file include to achieve remote code execution.

The course participation report required additional checks to prevent roles being displayed which the user did not have access to view.

Students in "Only see own membership" groups could see other students in the group, which should be hidden.

Wiki comments required additional sanitizing and access restrictions to prevent a stored XSS risk and potential IDOR risk.
