    Published: 30 Oct 2026Last Modified: 7 Nov 2026

    Summary: Moodle through 5.3.0, 5.2.4, 5.1.8, 5.0.11 and 4.5.15 Information Disclosure via core_grades_get_feedback

    Details: Moodle 4.2.0 through 4.5.15, 5.0.0 through 5.0.11, 5.1.0 through 5.1.8, 5.2.0 through 5.2.4, and 5.3.0 contain an information disclosure vulnerability in the core_grades_get_feedback web service. The service lacks group-membership and enrolment checks, so non-editing teachers can iterate userid values to read other groups' grade feedback and users' names and identity fields such as email.
