Model instances and querysets? I cannot think of any dangerous methods that can be called without arguments, but I am far from sure. If its not designed for it its probably not safe to do it. I suppose I could wrap something around these to restrict the methods available. > You could also automate checking of any tag libraries loaded against a > list of those you have deemed safe.

That is what I am most worried about :( The specific problem of nested loops also does not seem to have a solution. > > Bill > > On 1/26/12, graeme <graeme.piete...@gmail.com> wrote: > > > > > > > > > Are Django templates safe enough to use templates provided by > > untrusted users?
