  - CVE-2023-1402 / MSA-23-0012: The course participation report required additional checks to prevent
  roles being displayed which the user did not have access to view.

  - CVE-2023-28329 / MSA-23-0004: Insufficient validation of profile field availability condition
  resulted in an SQL injection risk (by default only available to teachers and managers).

  - CVE-2023-28330 / MSA-23-0005: 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.

  - CVE-2023-28331 / MSA-23-0006: Content output by the database auto-linking filter required
  additional sanitizing to prevent an XSS risk.

  - CVE-2023-28332 / MSA-23-0007: If the algebra filter was enabled but not functional (eg the
  necessary binaries were missing from the server), it presented an XSS risk.

  - CVE-2023-28333 / MSA-23-0008: 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).

  - CVE-2023-28336 / MSA-23-0011: Insufficient filtering of grade report history made it possible for
  teachers to access the names of users they could not otherwise access.");
