Cross-install user tracking via persistent cache state

Published Nov 4, 2025 · Updated Nov 4, 2025

Information disclosure in Apple TV Remote in Apple iOS and iPadOS before 26.1 allows attackers to track users between installs. The component handles cache state in a way that preserves a tracking signal across removal and reinstallation; Apple has not disclosed the specific cache or operation involved. Exploitation requires a malicious app to run on an affected iPhone or iPad, and the documented consequence is cross-install user tracking.
