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
McAfee Safe Connect before 2.16.1.126 may allow an adversary with system privileges to achieve privilege escalation by loading arbitrary DLLs.

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

McAfee Safe Connect before version 2.16.1.126 contains a DLL hijacking vulnerability where the application loads dynamic link libraries without proper path validation. An attacker with system-level access can place a malicious DLL in a location where the application will load it, achieving privilege escalation to higher integrity levels.

MitigationUpgrade McAfee Safe Connect to version 2.16.1.126 or later to resolve the insecure DLL loading behavior.

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 McAfee Safe Connect is installed
    Check for McAfee Safe Connect in the list of installed programs via Windows Settings > Apps > Apps & features, or query the Windows registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for a display name containing 'McAfee Safe Connect'
    Affected if McAfee Safe Connect is not present on the system (not vulnerable)
  2. Find the installed version number
    Right-click the Safe Connect executable (typically named SafeConnect.exe or similar in the installation directory, commonly under C:\Program Files\McAfee\Safe Connect\ or C:\Program Files (x86)\McAfee\Safe Connect\) and select Properties > Details to view the File Version, or query the Version registry value under the uninstall registry key
    Affected if Unable to determine the version (requires further investigation)
  3. Compare version to affected range
    Compare the installed version number to the affected range: any version lower than 2.16.1.126 is vulnerable. Version 2.16.1.126 and later are not affected
    Affected if The installed version is less than 2.16.1.126 (for example, 2.16.1.125, 2.15.x, 2.14.x, etc.)

The system is affected if McAfee Safe Connect is installed and the version is below 2.16.1.126, since the insecure DLL loading behavior exists in those versions.
