I seem to recall hearing in the past that unpickling in general was

I'd like to allow less-priveleged users to upload their ZEXP files on

Are there any security issues with ZEXP import?

You heard correctly; pickles can contain arbitrary python classes and
code and no security checks are done when importing ZEXP files. This
means a user can completely control your server with a correctly
crafted upload.
