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
A privacy issue was addressed by removing sensitive data. This issue is fixed in Xcode 16. An attacker may be able to determine the Apple ID of the owner of the computer.

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 vulnerability in Xcode versions prior to 16 allowed an attacker to potentially determine the Apple ID of the computer owner through exposure of sensitive data in the development environment. The issue was addressed by removing the sensitive data from the affected component.

MitigationUpdate to Xcode 16 or later to receive the privacy fix that removes sensitive Apple ID exposure.

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 installed Xcode version
    Open Xcode, then go to Xcode menu > About Xcode to view the version number. Alternatively, run 'xcodebuild -version' in Terminal.
    Affected if The displayed version is earlier than 16.0 (for example, 15.x, 14.x, etc.)
  2. Verify Xcode version meets the secure threshold
    Compare your installed Xcode version against the affected range. The vulnerability exists in all versions prior to 16.0.
    Affected if Your Xcode version is below 16.0 - you are running a version that contains the sensitive data exposure issue.

You are affected if your installed Xcode version is any release prior to 16.0, as those versions contain the component that exposes the Apple ID information.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
