Privilege escalation via unauthorized ContentProvider update
Published Jun 1, 2023 · Updated Jan 9, 2025
Privilege escalation in Glitter Unicorn Wallpaper 7.0 through 8.0 allows attackers to alter preference data through another installed app. The content provider processes ContentResolver update requests at its wall URI from unauthorized apps and writes the supplied nama value into the preference database. A malicious app must run on the same Android device; tampered values load when the wallpaper app opens, enabling misuse of the wallpaper app's privileges.
