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
The issue was addressed with improved routing of Safari-originated requests. This issue is fixed in Safari 18.2, iOS 18.2 and iPadOS 18.2, iPadOS 17.7.3, macOS Sequoia 15.2. On a device with Private Relay enabled, adding a website to the Safari Reading List may reveal the originating IP address to the website.

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

When Private Relay is enabled in Safari, adding a website to the Reading List can bypass the Private Relay tunnel and expose the user's originating IP address to the target website. The vulnerability stems from improper routing of Safari Reading List requests that should have been anonymized through Private Relay.

MitigationUpdate affected devices to Safari 18.2, iOS 18.2, iPadOS 18.2, iPadOS 17.7.3, or macOS Sequoia 15.2 to receive the improved routing fix.

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 the Safari version
    Open Safari, go to Safari > About Safari (on Mac) or Settings > Safari > About (on iOS/iPadOS) to view the version number
    Affected if The version is below 18.2 for Safari, or the iOS/iPadOS version is below 17.7.3 or below 18.2 but at or above 18.0, or macOS is below 15.2 but at or above 15.0
  2. Check if Private Relay is enabled
    On Mac: go to Safari > Settings > Privacy and verify the 'Hide IP address from trackers' option is enabled. On iOS/iPadOS: go to Settings > Safari > Privacy & Security and verify 'Hide IP Address' is set to 'From Trackers' or 'From Trackers and Websites'
    Affected if Private Relay (Hide IP Address) is turned on in Safari settings
  3. Verify Reading List functionality usage
    Check if the Reading List feature has been used - look for the Reading List icon in Safari's sidebar or toolbar, or check for saved articles
    Affected if Any websites have been added to the Reading List while Private Relay was enabled on a vulnerable version

Upgrade available Upgrade to 15.2 / 17.7.3 / 18.2 or later
Fixed in 15.217.7.318.2
Interim mitigation

Update affected devices to Safari 18.2, iOS 18.2, iPadOS 18.2, iPadOS 17.7.3, or macOS Sequoia 15.2 to receive the improved routing fix.

Recommended fix High confidence

Safari 18.2, iOS 18.2, iPadOS 18.2, iPadOS 17.7.3, or macOS Sequoia 15.2 depending on device

  1. For Safari on macOS: Open the App Store, click Updates, and install the Safari 18.2 update, or go to System Settings > General > Software Update and install macOS Sequoia 15.2
  2. For iPhone: Go to Settings > General > Software Update and install iOS 18.2
  3. For iPad: Go to Settings > General > Software Update and install iPadOS 18.2 (or iPadOS 17.7.3 for older devices)
  4. Alternatively, ensure Automatic Updates are enabled in System Settings/Preferences to receive future security updates automatically
  5. After updating, verify Private Relay remains enabled in Safari settings if previously configured
Caveat Standard Apple update considerations apply - ensure backups before updating, and note that older devices may not support the latest OS versions
