github.com/mattermost/mattermost-server is vulnerable to Improper Check For Unusual Or Exceptional Conditions. The vulnerability is caused due to a failure to restrict the input in POST /api/v4/users
which allows a user to manipulate the creation date in POST /api/v4/users
tricking the admin into believing their account is much older.
