User fingerprinting privacy issue in Apple Find My

IdentifiersCVE-2025-43507CWE-200

CVE-2025-43507 is a privacy vulnerability in Apple platforms, attributed in the provided content to Find My, that may allow a malicious app to fingerprint the user. Apple states the issue was addressed by moving sensitive data, indicating that application-accessible data exposed stable or distinguishing characteristics that could be used to derive a device- or user-specific fingerprint. The issue affects watchOS 26.1, macOS Tahoe 26.1, iOS 26.1 and iPadOS 26.1, iOS 18.7.2 and iPadOS 18.7.2 prior to the fix.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an app to derive identifying characteristics about the user or device and use them for fingerprinting. This can undermine platform privacy protections by enabling tracking or re-identification of a user across app sessions or potentially across installs, even without direct access to more obviously sensitive identifiers. The primary impact is loss of privacy rather than code execution or privilege escalation.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting installation and execution of untrusted or unnecessary apps, especially those that may access affected framework functionality. Enterprise controls such as application allow-listing and MDM-enforced update policies can reduce risk. However, no complete mitigation is provided in the content short of installing Apple's updates.

Remediation

Patch, then assume compromise.

Apply the vendor fixes provided by Apple. According to the supplied content, the issue is fixed in watchOS 26.1, macOS Tahoe 26.1, iOS 26.1 and iPadOS 26.1, iOS 18.7.2 and iPadOS 18.7.2. Upgrading affected devices to these versions or later remediates the vulnerability.
