Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An authentication issue was addressed with improved state management. This issue is fixed in iOS 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, visionOS 2.4. An attacker on the local network may be able to bypass authentication policy.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a local network authentication bypass vulnerability in Apple operating systems. An attacker positioned on the same local network could exploit improper authentication state management to bypass authentication policies and gain unauthorized access to protected resources or features.

MitigationApply the available security updates (iOS 18.4/iPadOS 17.7.6+, macOS 13.7.5/14.7.5/15.4+, tvOS 18.4, visionOS 2.4) to all affected devices. Until patched, restrict network access from untrusted devices and monitor for unauthorized access attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check iPhone or iPad OS version
    Go to Settings > General > About on the iOS/iPadOS device and note the version number (e.g., 18.3.1, 17.5)
    Affected if Version is < 17.7.6 OR (>= 18.0 AND < 18.4)
  2. Check macOS version
    Click Apple menu > About This Mac and note the version number (e.g., 15.3, 14.6)
    Affected if Version is < 13.7.5 OR (>= 14.0 AND < 14.7.5) OR (>= 15.0 AND < 15.4)
  3. Check tvOS version
    Open Settings > General > About > Version on Apple TV
    Affected if Version is < 18.4
  4. Check visionOS version
    Open Settings > General > About > Version on Apple Vision Pro
    Affected if Version is < 2.4
  5. Identify network-accessible authentication services
    Review device settings for any services that allow network authentication (e.g., AirDrop, HomeKit, file sharing, remote management profiles) and note if they are enabled
    Affected if Any network-authenticated service is accessible from the local network on a vulnerable OS version

The device is affected if it runs a vulnerable OS version AND has network-accessible authentication services enabled that could be reached by an attacker on the same local network.

Interim mitigation

Apply the available security updates (iOS 18.4/iPadOS 17.7.6+, macOS 13.7.5/14.7.5/15.4+, tvOS 18.4, visionOS 2.4) to all affected devices. Until patched, restrict network access from untrusted devices and monitor for unauthorized access attempts.

Recommended fix High confidence

iOS 18.4/iPadOS 18.4/iPadOS 17.7.6, macOS Ventura 13.7.5/macOS Sonoma 14.7.5/macOS Sequoia 15.4, tvOS 18.4, or visionOS 2.4 depending on device type and current version

  1. Identify the affected Apple device (iPhone, iPad, Mac, Apple TV, or Apple Vision Pro)
  2. Determine the current OS version installed on the device (go to Settings > General > About on iOS/iPadOS, or System Settings > About on macOS, or Settings > General on tvOS/visionOS)
  3. For iPhone devices: upgrade to iOS 18.4
  4. For iPad devices: upgrade to iPadOS 18.4 (if on iOS 18.x) or iPadOS 17.7.6 (if on iOS 17.x)
  5. For Mac computers: upgrade to macOS Ventura 13.7.5, macOS Sonoma 14.7.5, or macOS Sequoia 15.4 depending on your current major version
  6. For Apple TV: upgrade to tvOS 18.4
  7. For Apple Vision Pro: upgrade to visionOS 2.4
  8. After upgrading, verify the new version is installed by checking Settings > General > About
Caveat Standard OS upgrade considerations apply - review release notes for feature changes and ensure compatibility with critical applications before upgrading
