CVE-2023-27108Public exploitNetwork attack vector

Call-log disclosure via unrestricted Web Activity

Published May 1, 2023 · Updated Jan 30, 2025

Information disclosure in KaiOS 3.0 allows remote attackers to read call logs through the Communications app's Web Activity. The manifest exposes getCallLogList without allowedOrigins, and its service worker calls db.getAllData() and returns the result to any caller. A malicious website or app can invoke the activity without permission or user interaction and transmit telephone numbers, timestamps, call types, and durations to a remote server.
