The whole thing was leaking and falling apart at that point. That's sort of the lesson of the story.

Erso and the pilot leaked the whole thing to Saw anyway. Presumably, there were dozens of other security failures, departmental bickering and crossfire, defections, etc.

Sure, Krennic would love to blame it all on one ISB employee and one folder full of incriminating emails, but that doesn't happen in a vacuum.
