The lesson module in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2 allows remote authenticated users to bypass intended access restrictions and enter additional answer attempts by leveraging the student role.
Multiple cross-site scripting (XSS) vulnerabilities in the SCORM module in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1 allow remote attackers to inject arbitrary web script or HTML via a crafted organization name to (1) mod/scorm/player.php or (2) mod/scorm/prereqs.php.
Cross-site scripting (XSS) vulnerability in the user_get_user_details function in user/lib.php in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1 allows remote attackers to inject arbitrary web script or HTML by leveraging absence of an external_format_text call in a web service.

Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.4.0 through 2.8.1, as used in Bugzilla, Moodle, and other products, allows remote attackers to inject arbitrary web script or HTML via vectors related to charts/assets/charts.swf.
Cross-site scripting (XSS) vulnerability in the Flash component infrastructure in YUI 2.5.0 through 2.8.1, as used in Bugzilla, Moodle, and other products, allows remote attackers to inject arbitrary web script or HTML via vectors related to uploader/assets/uploader.swf.
