Live › vulnerability › CVE-2026-119555
The core_grades_get_feedback web service in Moodle skips group-membership and enrolment checks. A non-editing teacher can iterate userid values to read other groups' grade feedback and users' names and email addresses.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-30 12:30 UTC. All times on this page are UTC.
Moodle sites running 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, or 5.3.0 are exposed. The attacker must be a logged-in non-editing teacher who can call the grade feedback web service. Sites without such users or without the web service exposed are less at risk.

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.
