A recent UCP Security vulnerability was found and reported to UAT on Friday. The website was taken down while we work on resolving the security issue. The security issue was not used maliciously by the individual that reported it however it was open to the public to abuse. So it is possible that unintentional access to user data may have occurred.
We expect the website to be back up by Monday.
It is important that all users change passwords on both the MTA Server and the Forums as they were vulnerable from this security hole. Although passwords are hashed it is an important step to change your passwords regularly and especially after such a breach occurs.
