Moodle Exposure of Sensitive Information to an Unauthorized Actor
The advisory, in context
In Moodle 3.x, students can find out email addresses of other students in the same course. Using search on the Participants page, students could search email addresses of all participants regardless of email visibility. This allows enumerating and guessing emails of other students.
