  - CVE-2025-3625 / MSA-25-0014: A missing check in the Multi-Factor Authentication email factor's
  revoke/cancel action could lead to a Denial of Service risk for users logging in who have email
  as their only available second factor. If exploited, the impacted user's name was disclosed.

  - CVE-2025-3627 / MSA-25-0015: On sites with Multi-Factor Authentication enabled, it is possible
  for a user to access some of their data after passing only the first login factor (such as
  passing a username/password check). The user should have to also pass a second factor check
  before gaining access to that data.

  - CVE-2025-3634 / MSA-25-0017: On sites with Multi-Factor Authentication enabled, it is possible
  to use course self enrolment after passing only the first login factor (such as passing
  a username/password check). The user should also have to pass a second login factor before
  gaining access to self enrolment.");
