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 logic issue was addressed with improved state management. This issue is fixed in Xcode 15.3. An app may bypass Gatekeeper checks.

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

A logic error in Xcode's state management allows a crafted application to bypass macOS Gatekeeper checks, which normally verify that apps are from identified developers and have not been tampered with. This could permit untrusted or malicious code to execute on macOS systems.

MitigationUpdate to Xcode 15.3 or later, which contains the fix for the state management logic flaw that enabled Gatekeeper bypass.

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
    Run 'xcodebuild -version' in Terminal to see the currently installed Xcode version
    Affected if The version shown is less than 15.3 (for example, 15.2, 15.1, 15.0, or any version before 15.3)
  2. Verify Xcode application location
    Confirm the Xcode installation is at /Applications/Xcode.app - the vulnerability applies to the main Xcode installation used for building and code signing
    Affected if Xcode is installed at the standard location and its version is below 15.3

If the installed Xcode version is any release earlier than 15.3, the environment contains the vulnerable state management logic that could allow Gatekeeper bypass.

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.

Upgrade available Upgrade to 15.3 or later
Fixed in 15.3
Interim mitigation

Update to Xcode 15.3 or later, which contains the fix for the state management logic flaw that enabled Gatekeeper bypass.

Recommended fix High confidence

Xcode 15.3

  1. Download Xcode 15.3 from the Mac App Store or Apple Developer website
  2. Launch Xcode 15.3 and verify installation under Xcode > About Xcode
  3. Ensure the new version is selected in Xcode > Preferences > Locations > Command Line Tools if applicable
  4. Clean and rebuild any existing projects to ensure they work with the updated toolchain
Caveat Review release notes for any deprecations or toolchain changes that may affect existing projects
