# Apple iOS and macOS: malicious app can bypass certificate validation

Apple's advisory says a logic flaw in state management lets a malicious app bypass certificate validation on iOS, iPadOS, macOS and visionOS. An attacker who gets a malicious app onto a device could impersonate servers and intercept connections that rely on that validation.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed OS version under Settings > General > About (iOS, iPadOS, visionOS) or `sw_vers -productVersion` on macOS, and compare it to the fixed versions below.

## Fix

- Update iOS and iPadOS to `26.7.2` or `27.2`.
- Update macOS Tahoe to `26.7.2`, macOS Sequoia to `15.8.2`, and macOS Golden Gate to `27.2`.
- Update visionOS to `27.2`.
