CVE-2025-48612

Local privilege escalation via payment-selector string injection

Published Dec 8, 2025 · Updated Jun 1, 2026

Improper input validation in Android 14, 15, 16, and 16-qpr2 allows local users to change the main user's default NFC payment app. DefaultPaymentSettings.setDefaultKey splits an attacker-controlled selector string and passes its component and user ID directly to PaymentBackend instead of resolving a known payment-app entry. A malicious application in a work profile can target the main profile without user interaction or additional execution privileges.
