CVE-2023-27652Public exploit

Persistent app crash via SharedPreference data injection

Published Apr 20, 2023 · Updated Feb 5, 2025

Denial of service in Ego Studio SuperClean 1.1.5 and 1.1.9 allows local users to persistently crash the app via SharedPreferences. A malicious Android app repeatedly inserts large key-value pairs through SharedPrefProvider into default.xml, which SuperClean loads into memory until an out-of-memory error occurs. User interaction is required; the injected data persists across restarts and prevents the app from launching, with no reported confidentiality or integrity impact.
