Recently WHMCS released a security update that has been marked as Trivial to Important on their security level scale. This should be addressed immediately if you are running a version older than 6.2.1. You may perform this update within WHMCS or within Softaculous if that is how you installed the software. If you have any questions feel free to contact our support department.
Once sufficient time has passed, WHMCS will update their security release notes with more information on the flaws that provoked this security update.
