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 permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sonoma 14. A sandboxed process may be able to circumvent sandbox restrictions.

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 macOS where a sandboxed process can circumvent sandbox restrictions due to a permissions issue. The vulnerability allows a process that should be confined to break out of its sandbox, potentially accessing resources outside its intended permission boundaries.

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 macOS version
    Run 'sw_vers -productVersion' in Terminal, or open Apple menu > About This Mac
    Affected if The version returned is below 14.0 (such as 13.x, 12.x, or earlier)
  2. Confirm system is running a vulnerable macOS release
    Compare the installed version against the affected range: any version less than 14.0
    Affected if The installed macOS version is 13.x or earlier

If the system is running macOS versions prior to 14.0, the sandbox escape vulnerability is present and the environment is affected.
