Persistent crash via unrestricted content-provider inserts
Published Jun 1, 2023 · Updated Jan 9, 2025
Data injection in Glitter Unicorn Wallpaper 7.0 through 8.0 allows attackers to persistently crash the app via a malicious Android app. The content provider accepts unrestricted insert requests at its wall URI, stores attacker-controlled image URLs in the preferences database, and loads the growing dataset into memory when the wallpaper app opens. Exploitation requires another application on the same Android device; repeated inserts exhaust memory, and malicious records survive restarts to trigger recurring crashes.
