A remote code execution risk was identified in the Shibboleth authentication plugin. (Note: Shibboleth authentication is disabled by default in Moodle.)

The file repository's URL parsing required additional recursion handling to mitigate the risk of recursion denial of service.

Insufficient redirect handling made it possible to blindly bypass cURL blocked hosts/allowed ports restrictions, resulting in a blind SSRF risk. (Note: The request response was still blocked and not available to the user.)

Insufficient capability checks meant message deletions were not limited to the current user.

ID numbers displayed in the web service token list required additional sanitizing to prevent a stored XSS risk.

ID numbers displayed in the quiz override screens required additional sanitizing to prevent a stored XSS risk.

Insufficient capability checks made it possible to remove other users' calendar URL subscriptions.

ID numbers exported in HTML data formats required additional sanitizing to prevent a local stored XSS risk. Note that the XSS was part of the locally downloaded file and not on the Moodle site's domain.

Users' names required additional sanitizing in the account confirmation email, to prevent a self-registration phishing risk.

In some circumstances, email notifications of messages could have the link back to the original message hidden by HTML, which may pose a phishing risk.
