  - CVE-2024-25978: Insufficient file size checks resulted in a denial of service risk in the file
  picker's unzip functionality.

  - CVE-2024-25979: The URL parameters accepted by forum search were not limited to the allowed
  parameters.

  - CVE-2024-25980: Separate Groups mode restrictions were not honoured in the H5P attempts report,
  which would display users from other groups. By default this only provided additional access to
  non-editing teachers.

  - CVE-2024-25981: Separate Groups mode restrictions were not honoured when performing a forum
  export, which would export forum data for all groups. By default this only provided additional
  access to non-editing teachers.

  - CVE-2024-25982: The link to update all installed language packs did not include the necessary
  token to prevent a CSRF risk.

  - CVE-2024-25983: Insufficient checks in a web service made it possible to add comments to the
  comments block on another user's dashboard when it was not otherwise available (eg on their
  profile page).");
