A security exploit was found by Han Sahin of www.SumOfPwn.nl

It probably tooks a month to fix all the staff related to that, so you should disable the plugin for being protected.

You could ckeck the Git repository for daily works https://github.com/lechab/newstatpress and eventully for use the code as soon as it is fixed.

Thanks

[Update] You can use the current build that fix the exploite: newstatpress-master

Install it as soos as possible.
