This is due to improper user check error handling in the two-factor REST API actions with the 'check\_login\_and\_get\_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, when the "Two-Factor Authentication" setting is enabled (disabled by default).
