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
This issue was addressed with improved checks. This issue is fixed in Xcode 26. An app may be able to break out of its sandbox.

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 sandbox escape vulnerability in Xcode. The issue allows a malicious or compromised application to break out of its sandbox and potentially execute code with elevated privileges outside the intended security boundary. The vulnerability was addressed with improved checks and is fixed in Xcode 26.

MitigationUpgrade to Xcode 26 or later to obtain the fixed version with the improved sandbox checks.

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 if Xcode is installed
    Run 'xcode-select -p' in Terminal or look for Xcode.app in /Applications
    Affected if Xcode is not found - the vulnerability does not apply to this environment
  2. Determine the installed Xcode version
    Run 'xcodebuild -version' in Terminal or open Xcode and go to Xcode > About Xcode
    Affected if Unable to determine version - manual verification required
  3. Compare version against affected range
    Verify the reported version number is below 26.0 (such as 25.x, 24.x, or earlier)
    Affected if Installed version is less than 26.0 - the environment is affected by this sandbox escape vulnerability

A user is affected if Xcode is installed and the version is below 26.0, as this allows a malicious application to potentially escape its sandbox and execute code with elevated privileges.
