Security announcements | Moodle.org

The TinyMCE editor included with Moodle required a security patch to be applied to fix an XSS risk.

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

Insufficient filtering of grade report history made it possible for teachers to access the names of users they could not otherwise access.

The link to reset all templates of a database activity did not include the necessary token to prevent a CSRF risk.

Authenticated users were able to enumerate other users' names via the learning plans page.

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).
