User fingerprinting via undisclosed privacy-control flaw
Published Dec 12, 2025 · Updated Dec 12, 2025
Information disclosure in Apple iOS and iPadOS before 26.1 allows local users to fingerprint a device user through an installed app. The flaw resides in Managed Configuration, but Apple has not disclosed which data the privacy controls expose or which operation makes that data available. Exploitation requires low-privileged local app execution, and the reported consequence is limited to user fingerprinting rather than data modification or service interruption.
