CSRF attack error message in Dev Environment

Currently in the dev environment - I and several other developers have encountered the CSRF attack error when doing certain actions. This is not an issue in our UAT or Live environments and we're struggling to pin this down and was wondering if anyone here could give us some pointers.

Stack Trace from the Kentico event log is below:

Message: CSRF attack detected.
