mod/quiz/db/access.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 does not set the RISK_XSS bit for graders, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via crafted gradebook feedback during manual quiz grading.

Security readout for executives and security teams

Older Moodle sites may let an authenticated user place script content into gradebook feedback during manual quiz grading. If a grader views that feedback, the script could run in the grader’s browser. This is a role and workflow-specific XSS issue, not an unauthenticated server takeover based on the provided sources. Exposure is likely limited to legacy Moodle deployments running the affected versions and using quiz manual grading workflows. The attacker must be authenticated, and impact depends on whether crafted feedback is viewed by a user with grader privileges. Treat this as a legacy Moodle remediation item with moderate business urgency. Prioritize internet-facing or widely used learning platforms, especially where many authenticated users can submit quiz content and graders use privileged sessions. Mitigation focus: Upgrade Moodle 2.6.x to 2.6.11 or later.; Upgrade Moodle 2.7.x to 2.7.8 or later.; Upgrade Moodle 2.8.x to 2.8.6 or later..
