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
Alludo Parallels Desktop before 19.4.2 and 20.x before 20.2.2 for macOS on Intel platforms allows privilege escalation to root via the VM creation routine.

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 · high confidence

A local privilege escalation vulnerability exists in Parallels Desktop for macOS on Intel platforms. The flaw in the VM creation routine allows an authenticated local user to gain root privileges by exploiting improper privilege handling during virtual machine creation.

MitigationUpdate Parallels Desktop to version 19.4.2 or 20.2.2 or later to remediate this vulnerability. As this is a local privilege escalation, network-based controls are not applicable; patching is the primary remediation path.

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. Verify Parallels Desktop is installed
    Check for Parallels Desktop application in /Applications folder, or run 'ls /Applications | grep -i parallels'
    Affected if Parallels Desktop is present on the system
  2. Determine installed Parallels Desktop version
    Run 'prlctl --version' or right-click Parallels Desktop.app > Get Info to view version number
    Affected if Version is 19.x before 19.4.2, or 20.x before 20.2.2, or any version older than these release points
  3. Confirm system uses Intel processor
    Run 'sysctl -n machdep.cpu.brand_string' or check System Information > Processor. Apple Silicon Macs are not affected.
    Affected if System is Intel-based and Parallels Desktop version is in the affected range listed above
  4. Verify VM creation capability is accessible
    Confirm the user account has access to create VMs in Parallels - this is a standard user capability in Parallels Desktop
    Affected if User can access Parallels Desktop and create virtual machines on the affected version

User is affected if running Parallels Desktop on an Intel-based Mac with version 19.x before 19.4.2 or version 20.x before 20.2.2, where an authenticated local user can leverage VM creation to escalate privileges.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Parallels Desktop to version 19.4.2 or 20.2.2 or later to remediate this vulnerability. As this is a local privilege escalation, network-based controls are not applicable; patching is the primary remediation path.

Recommended fix High confidence

Parallels Desktop 19.4.2 or 20.2.2 (or later)

  1. Open Parallels Desktop and go to the menu bar, click Parallels Desktop > Check for Updates
  2. If an update is available, download and install Parallels Desktop 19.4.2 or later (for version 19.x) or 20.2.2 or later (for version 20.x)
  3. Alternatively, download the latest version directly from kb.parallels.com or the official Parallels website
  4. Restart your Mac after installation to ensure the update is fully applied
  5. Verify the installed version by going to Parallels Desktop > About Parallels Desktop and confirm the version number meets the fixed release requirements
Caveat Review release notes for any VM configuration or compatibility changes before upgrading; ensure VMs are backed up
