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
Privilege Escalation vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 Hotfix 199847 allows local users to delete files the user would otherwise not have access to via manipulating symbolic links to redirect a McAfee delete action to an unintended file. This is achieved through running a malicious script or program on the target machine.

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

Local privilege escalation in McAfee Endpoint Security for Windows allows authenticated users to delete arbitrary files they lack permissions for by manipulating symbolic links. The vulnerability exploits ENS's delete functionality through symlink redirection, enabling a low-privilege user to cause McAfee to delete files outside their intended scope.

MitigationUpdate McAfee Endpoint Security for Windows to version 10.7.0 Hotfix 199847 or later to patch the symbolic link handling vulnerability.

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 McAfee Endpoint Security version
    Open Windows Registry and navigate to HKLM\SOFTWARE\McAfee\Endpoint_Securities\ or use 'Get-ItemProperty' in PowerShell at 'HKLM:\SOFTWARE\McAfee\Endpoint_Securities\' to find the 'ProductVersion' value. Alternatively, open Programs and Features in Control Panel and locate McAfee Endpoint Security to view the installed version.
    Affected if The installed version is 10.5.0 through 10.5.4, equals 10.6.0, or equals 10.7.0 (and is not patched with Hotfix 199847 or later).
  2. Verify ENS file control or quarantine feature is enabled
    Open McAfee Endpoint Security console (EPO or local UI) and check the status of File Control or Quarantine settings under the Threat Prevention or Adaptive Threat Protection section. This can also be checked via registry at HKLM\SOFTWARE\McAfee\Endpoint_Securities\Policy\ if accessible.
    Affected if The File Control, Quarantine, or Adaptive Threat Protection feature is enabled, allowing ENS to perform file delete operations on behalf of users.
  3. Confirm user context can trigger file deletion operations
    Identify whether standard (non-admin) authenticated users on the system can trigger file deletion or quarantine actions through ENS. This typically involves checking if low-privilege users can access the ENS client interface or if automated response policies apply to user-triggered events.
    Affected if Standard authenticated users have the ability to interact with ENS in a way that triggers file deletion or quarantine operations.

If the installed McAfee Endpoint Security for Windows version falls within 10.5.0 to 10.5.4, equals 10.6.0, or equals 10.7.0, and file deletion/quarantine features are accessible to standard users, the environment is likely affected by this symlink redirection vulnerability.
