CVE-2018-11399
SimpliSafe Original has Unencrypted Sensor Transmissions, which allows physically proximate attackers to obtain potentially sensitive information about the specific times when alarm-system events occur.
Does this matter?
Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.
