CVE-2023-20932

Cross-user contact disclosure via overprivileged EmergencyInfo manifest

Published Feb 28, 2023 · Updated Mar 21, 2025

Improper input validation in EmergencyInfo on Google Android 10 through 13 allows local users to read other users' contacts. The EmergencyInfo manifest grants INTERACT_ACROSS_USERS_FULL, allowing EditInfoFragment.onCreatePreferences to access contact data across user profiles. A local application context is required; no user interaction or additional execution privileges are needed, and the impact is limited to contact disclosure.
