The Mustache pix helper contained a potential Mustache injection risk if combined with user input (note: This did not appear to be implemented/exploitable anywhere in the core Moodle LMS).

If the algebra filter was enabled but not functional (eg the necessary binaries were missing from the server), it presented an XSS risk.

Content output by the database auto-linking filter required additional sanitizing to prevent an XSS risk.

Insufficient sanitizing in backup resulted in an arbitrary file read risk. The capability to access this feature is only available to teachers, managers and admins by default.

Insufficient validation of profile field availability condition resulted in an SQL injection risk (by default only available to teachers and managers).

The course participation report required additional checks to prevent roles being displayed which the user did not have access to view.

The vulnerability was found Moodle which exists due to insufficient limitations on the "start page" preference. A remote attacker can set that preference for another user. The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in blog search. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in some returnurl parameters. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a remote attacker to perform cross-site scripting (XSS) attacks.

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.

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.

SQL injection vulnerability in ing/blocks/mrbs/code/web/view_entry.php in the MRBS plugin for Moodle allows remote attackers to execute arbitrary SQL commands via the id parameter.
