  - CVE-2023-5539 / MSA-23-0031: A remote code execution risk was identified in the Lesson activity.
  By default this was only available to teachers and managers.

  - CVE-2023-5540 / MSA-23-0032: A remote code execution risk was identified in the IMSCP activity.
  By default this was only available to teachers and managers.

  - CVE-2023-5541 / MSA-23-0033: The CSV grade import method contained an XSS risk for users
  importing the spreadsheet, if it contained unsafe content.

  - CVE-2023-5544 / MSA-23-0036: Wiki comments required additional sanitizing and access restrictions
  to prevent a stored XSS risk and potential IDOR risk.

  - CVE-2023-5545 / MSA-23-0037: H5P metadata automatically populated the author with the user's
  username, which could be sensitive information.

  - CVE-2023-5547 / MSA-23-0039: The course upload preview contained an XSS risk for users uploading
  unsafe data.

  - CVE-2023-5548 / MSA-23-0040: Stronger revision number limitations were required on file serving
  endpoints to improve cache poisoning protection.

  - CVE-2023-5549 / MSA-23-0041: Insufficient escaping of users' names in account confirmation
  email.

  - CVE-2023-5550 / MSA-23-0042: In a shared hosting environment that has been misconfigured to allow
  access to other users' content, a Moodle user who also has direct access to the web server
  outside of the Moodle webroot could utilise a local file include to achieve remote code execution.

  - CVE-2023-5551 / MSA-23-0043: Separate Groups mode restrictions were not honoured in the forum
  summary report, which would display users from other groups.");
