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. Determine macOS version via command line
    Run 'sw_vers -productVersion' in Terminal to get the exact version number (e.g., 12.5.1)
    Affected if The version falls within 11.0-11.7.6, 12.0-12.6.5, or 13.0-13.3
  2. Get detailed system information
    Run 'system_profiler SPSoftwareDataType' and look for the System version entry
    Affected if The reported version matches any of the vulnerable version ranges listed in the CVE
  3. Confirm patch status
    Check Apple security updates: open System Settings > General > Software Update, or visit Apple's security releases page
    Affected if No security update for this CVE has been applied and the version remains in the affected range

A system is affected if it runs macOS Big Sur 11.0-11.7.6, Monterey 12.0-12.6.5, or Ventura 13.0-13.3 without the corresponding security patch installed.
