CVE-2026-82850 Details

ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

The Masteriyo LMS WordPress plugin before 3.4.2 does not restrict access to quiz answer keys, allowing any authenticated user, such as a student, to retrieve the correct answers for any quiz on the site, including quizzes in courses they are not enrolled in. The redaction that hides them is applied only to a fixed list of question types, so the answers to every other type are returned in full to anyone able to view the questions.
