GoogleOSV:GHSA-6R7X-6Q98-QCQPMoodle does not set the RISK_XSS bit for graders
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.
