While we endeavour to ensure that all code we push is secure, we can not promise that something may have been missed. Due to the open-source nature of PufferPanel it is possible for others to see the code and look for holes. We encourage anyone who finds a hole to immediately report it to us so we can do everything in our power to fix it.
An additional shout-out to the folks below who have provided countless hours of development help, suggestions, and motivation.
