Security

• In previous versions, RT's native login system is vulnerable to user enumeration
  through a timing side-channel attack. This means an external entity could try to
  find valid usernames by attempting logins and comparing the time to evaluate each
  login attempt for valid and invalid usernames. This vulnerability does not allow any
  access to the RT system. This vulnerability is assigned CVE-2021-38562 and is fixed
  in this release.
