Apple Watchos

CVE-2026-43679

This issue was addressed with improved permissions checking. This issue is fixed in watchOS 26.4. An attacker with physical access to a locked Apple Watch may be able to view user contacts.

What this means for your business

  • It affects Apple Watchos. It matters if your company, or a supplier that handles your data, runs it.
  • An attacker can use it only with physical access to the device, without a login, and without anyone at your company clicking anything.

What to do

  1. 1Check whether your company or your suppliers run Apple Watchos, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
