CVE-2025-43449 is a privacy flaw in iOS and iPadOS in which improper handling of caches could allow a malicious application to track a user across app reinstalls. Apple states the issue was addressed with improved handling of caches and fixed in iOS 26.1 and iPadOS 26.1. Based on the advisory text, the vulnerability appears to stem from cache state or identifiers persisting in a way that remains accessible or correlatable after an uninstall/reinstall cycle, defeating the expected privacy boundary between separate installations of the same app.
