CVE-2020-6812Public exploitNetwork attack vector

Personal-name disclosure via unsanitized AirPods device labels

Published Mar 25, 2020 · Updated Aug 4, 2024

Information disclosure in Mozilla Firefox before 74, Firefox ESR before 68.6, and Thunderbird before 68.6 allows remote attackers to read names. The WebRTC device-enumeration path returns an AirPods MediaDeviceInfo label verbatim instead of replacing the personalized device name. Exploitation requires connected AirPods with a personalized label and prior camera or microphone permission; disclosure is limited to the label text.
