Hi Ed, Thanks for making folks aware of this. Any self-managed environments on our recommended OS (Ubuntu 18.04) would be vulnerable, and should update as soon as practical. For any users on Dimagi's production clouds: our systems are autopatched and I can confirm that we were patched yesterday, so there's no concern or actions needed. ---

Good point on self hosted - I should probably have been specific, my apologies!
