[FREEBSD:909A80BA-6294-11ED-9CA2-6C3BE5272ACD] Grafana -- Improper authentication

Grafana Labs reports:

  On September 7, as a result of an internal security audit, we discovered
  a security vulnerability in Grafana’s basic authentication related to the usage
  of username and email address.
  n Grafana, a user’s username and email address are unique fields, which
  means no other user can have the same username or email address as another user.

  In addition, a user can have an email address as a username, and the Grafana
  login allows users to sign in with either username or email address. This
  creates an unusual behavior, where user_1 can register with one email
  address and user_2 can register their username as user_1’s
  email address. As a result, user_1 would be prevented from signing
  in to Grafana, since user_1 password won’t match with user_2
  email address.
  The CVSS score for this vulnerability is 4.3 moderate
  (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L).
