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 file handling. This issue is fixed in macOS Sequoia 15. 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

A logic error in file handling within macOS allows an application to escape its sandbox restrictions, potentially enabling arbitrary code execution with elevated privileges. This vulnerability was addressed in macOS Sequoia 15 through improved file handling controls.

MitigationApply macOS Sequoia 15 or later to affected systems to remediate the sandbox escape vulnerability. Prioritize systems running older macOS versions given the critical (CVSS 10) severity.

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 installed macOS version
    Run 'sw_vers -productVersion' in Terminal or go to Apple menu > About This Mac to view the macOS version number
    Affected if The version displayed is below 15.0 (for example, 14.x, 13.x, etc.)
  2. Confirm the full OS build number
    Run 'system_profiler SPSoftwareDataType' in Terminal to see both the marketing version and the build number
    Affected if The build version corresponds to a pre-Sequoia release (any build prior to macOS 15.0)
  3. Determine if third-party file handling extensions are active
    Check System Settings > Privacy & Security > Extensions > Added Extensions for any sandboxed applications with file handling capabilities enabled
    Affected if Any sandboxed applications with file handling extensions are installed on a macOS version below 15.0
  4. Verify system audit logs for sandbox violations
    Run 'sudo log show --predicate 'subsystem == "com.apple.security.sandbox"' --last 24h' to review recent sandbox-related events
    Affected if Any sandbox escape attempts or file handling anomalies appear in logs on systems running below macOS 15.0

A system is affected if it runs any macOS version prior to 15.0 (Sequoia), as the vulnerability allows sandboxed applications to bypass restrictions through improper file handling.
