Additional checks were required to ensure trusttext is applied (when enabled) to glossary entries being restored.

Insufficient capability checks made it possible to disable badges a user does not have permission to access.

The question bank filter required additional sanitizing to prevent a reflected XSS risk.

Description information displayed in the site administration live log required additional sanitizing to prevent a stored XSS risk.

The drag-and-drop onto image (ddimageortext) question type required additional sanitizing to prevent a stored XSS risk.

Tags not expected to be visible to a user could still be discovered by them via the tag search page or in the tags block.

Separate Groups mode restrictions were not factored into permission checks before allowing viewing or deletion of responses in Feedback activities.

Insufficient sanitizing in the TeX notation filter resulted in an arbitrary file read risk on sites where pdfTeX is available (such as those with TeX Live installed).

A vulnerability was found in Moodle. Additional checks are required to ensure users can only fetch the list of course badges for courses that they are intended to have access to.

A flaw was found in Moodle. When restricting access to a lesson activity with a password, certain passwords could be bypassed or less secure due to a loose comparison in the password-checking logic. This issue only affected passwords set to "magic hash" values.

A flaw was found in Moodle. Additional checks were required to ensure users can only delete their OAuth2-linked accounts.

A flaw was found in Moodle. Dynamic tables did not enforce capability checks, which resulted in users having the ability to retrieve information they did not have permission to access.

A vulnerability was found in Moodle. Additional checks are required to ensure users can only access the schedule of a report if they have permission to edit that report.

A vulnerability was found in Moodle. Users with access to delete audiences from reports could delete audiences from other reports that they do not have permission to delete from.
