Packages

Packagist moodle/moodle >= 2.7.0, < 2.7.3 2.7.3

Details

As written in the advisory (Markdown source, shown as plain text).

lib/classes/grades_external.php in Moodle 2.7.x before 2.7.3 does not consider the moodle/grade:viewhidden capability before displaying hidden grades, which allows remote authenticated users to obtain sensitive information by leveraging the student role to access the get_grades web service.
