Security readout for executives and security teams
CVE-2019-10188 is an access-control flaw in Moodle quiz group overrides. A teacher in one quiz group could modify overrides for other groups in the same quiz, creating unauthorized assessment changes. The issue is medium severity and mainly affects integrity, not confidentiality or availability. Exposure is likely limited to Moodle sites on versions earlier than 3.7.1, 3.6.5, or 3.5.7 that use quizzes with group overrides and teacher group assignments. Prioritize remediation during normal patch cycles unless quizzes are business-critical or high-stakes. The main risk is unauthorized assessment configuration changes, not system takeover or data theft. Mitigation focus: Upgrade Moodle to 3.7.1, 3.6.5, 3.5.7, or a later supported release.; Check Moodle's advisory and release notes for branch-specific upgrade guidance.; Review teacher roles on quizzes that use group overrides..
