CVE-2019-11749
A vulnerability exists in WebRTC where malicious web content can use probing techniques on the getUserMedia API using constraints to reveal device properties of cameras on the system without triggering a user prompt or notification.
Does this matter?
Lower severity and a low EPSS score (0.90%). Track it; it rarely justifies an emergency change on its own.
