Description
The core_grade component in Moodle through 2.2.10, 2.3.x before 2.3.7, and 2.4.x before 2.4.4 does not properly consider the existence of hidden grades, which allows remote authenticated users to obtain sensitive information by leveraging the student role and reading the Gradebook Overview report.
