Security issues are always a concern the question is how much. Looking at it they seem to at most be ways to circumvent the Anubis redirect system to get to your page using very specific exploits. These are marked as m low to moderate priority and I do not see anything that implies like system level access which is the big concern. Obviously do what you feel is best but IMO its not worth sweating about. Nice thing about open source projects is that anyone can look through and fix, if this gets more popular you can expect bug bounties and professional pen testing submissions.
