A remote code execution risk was identified in the Moodle LMS Dropbox repository. By default this was only available to teachers and managers, on sites with the Dropbox repository enabled.

Insufficient capability checks made it possible for a user enrolled in a course to access some details (full name and profile image URL) of other users they did not have permission to access.

The analysis request action in the Brickfield tool did not include the necessary token to prevent a CSRF risk.

A user's CSRF token was unnecessarily included in the URL on the database module's edit and delete pages.

Insufficient capability checks made it possible to view RSS feed content a user does not have permission to access.

The user tours duplicate tour action did not include the necessary token to prevent a CSRF risk.

On sites with Multi-Factor Authentication enabled, it was possible to use course self enrolment after passing only the first login factor (such as passing a username/password check). The user should also have to pass a second login factor before gaining access to self enrolment.

Additional capability checks were required to prevent teachers from being able to identify a user's anonymous assignment submissions via the submissions search.

On sites with Multi-Factor Authentication enabled, it was possible for a user to access some of their data after passing only the first login factor (such as passing a username/password check). The user should have to also pass a second factor check before gaining access to that data.

A missing check in the Multi-Factor Authentication email factor's revoke/cancel action could lead to a Denial of Service risk for users logging in who have email as their only available second factor. If exploited, the impacted user's name was disclosed.
