CacheFS & Security

I wonder what the security implications of CacheFS are. Does each file inherit the permissions of the original? Is confidentiality a problem? What if you want to securely erase a file?

Other than that CacheFS should preserve the same permissions semantics as if a given user/host were accessing the backend filesystem/service directly.
Not knowing anything about CacheFS internals, I would say these are cases of "don't do it, then". ;-)
CacheFS & Security
The only difference between accessing a filesystem directly and through CacheFS should be that the CacheFS can store copies of the accessed data on a local block device. In other words that there's a (potentially persistent) footprint of all accesses.CacheFS & Security
