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
Improper link resolution before file access ('link following') in Microsoft Edge (Chromium-based) allows an authorized attacker to elevate privileges locally.

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 link following (symlink manipulation) vulnerability in Microsoft Edge allows a local attacker with authorized access to escalate privileges by exploiting improper link resolution before file access, potentially enabling the attacker to access or modify files they shouldn't have permissions for.

MitigationApply Microsoft Edge security updates when released; in the interim, restrict local access to sensitive files and directories, and limit user privileges to minimize the attack surface.

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. Locate the Microsoft Edge Update component
    Check for the EdgeUpdate service or executable on the system. Common locations include C:\Program Files\Microsoft\EdgeUpdate\ or C:\Program Files (x86)\Microsoft\EdgeUpdate\. Also check Windows Services for 'Microsoft Edge Update Service'.
    Affected if The Edge Update component is installed on the system
  2. Find the installed Edge Update version via registry
    Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EdgeUpdate\ or HKEY_CURRENT_USER\SOFTWARE\Microsoft\EdgeUpdate\. Look for a value named 'pv' (product version) that shows the current version.
    Affected if The version shown is less than 1.3.195.45
  3. Find the installed Edge Update version via PowerShell
    Run PowerShell as administrator and execute: Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\EdgeUpdate' -ErrorAction SilentlyContinue | Select-Object pv. If not found under HKLM, try HKCU:\SOFTWARE\Microsoft\EdgeUpdate.
    Affected if The version returned is less than 1.3.195.45
  4. Check Edge Update executable version directly
    Locate the edgeupdate.exe file (commonly in C:\Program Files\Microsoft\EdgeUpdate\ or C:\Program Files (x86)\Microsoft\EdgeUpdate\) and right-click to view Properties, or run: (Get-Item 'C:\Program Files\Microsoft\EdgeUpdate\edgeupdate.exe').VersionInfo.FileVersion
    Affected if The executable version shown is less than 1.3.195.45

If the Microsoft Edge Update version is found to be lower than 1.3.195.45, the system is vulnerable to local privilege escalation via symlink manipulation.
