Parental control bypass via unlimited PIN guesses
Published Jul 1, 2025 · Updated Jul 1, 2025
Improper access control in Ullu 2.9.929 for Android and 2.8.0 for iOS allows local users to bypass the parental PIN. The PIN entry flow accepts unlimited guesses without rate limiting or account lockout, permitting exhaustive search of the four-digit value. Access to an authenticated account and interaction with the app are required; a successful guess disables the parental lock and exposes restricted content.
