Very, very bad vulnerability in Ubiquiti's Unifi Network app affecting all Unifi Dream Machine (UDM) models. Severity scale is out of 10 and I don't think I've ever seen a 10.0 like this before. Run don't walk to make sure you're patched folks: https://community.ui.com/releases/Security-Advisory-Bulletin-036-036/81367bc9-2a64-4435-95dc-bbe482457615
Automatic updates have been rolling out successfully, but make sure 1) you have automatic updates enabled, and 2) you're running version 7.5.187 of the Network app or later
