  default this was only available to teachers and managers.

  - CVE-2023-6664 / MSA-23-0047: Separate Groups mode restrictions were not honoured in the Logs
  and Live logs course reports, which would display users from other groups.

  - CVE-2023-6667 / MSA-23-0050: Separate Groups mode restrictions were not honoured in survey
  response reports, which would display users from other groups.

  - CVE-2023-6668 / MSA-23-0051: Insufficient capability checks meant it was possible for all users
  to view the recipients of badges.

  - CVE-2023-6669 / MSA-23-0052: The mtrace output when running a task in the admin UI required
  additional sanitizing to prevent an XSS risk.");
