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
Microsoft Edge allows remote attackers to bypass the Same Origin Policy via vectors involving the about:blank URL and data: URLs, aka "Microsoft Edge Elevation of Privilege Vulnerability."

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

Microsoft Edge contains a Same Origin Policy (SOP) bypass vulnerability that allows remote attackers to access content from different origins. The attack vector involves manipulating about:blank URLs in combination with data: URLs, allowing an attacker to violate the browser's security model and potentially steal sensitive cross-origin data or perform actions on behalf of the user.

MitigationApply Microsoft security updates for CVE-2017-0002 to patch the Edge browser. Until patched, avoid using Microsoft Edge for sensitive operations and consider using an alternative browser.

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 if Microsoft Edge is installed
    Open Windows Settings > Apps > Apps & features, or run 'Get-AppxPackage *MicrosoftEdge*' in PowerShell to list Edge installations
    Affected if Microsoft Edge is found on the system - all versions are affected by this CVE
  2. Determine the Microsoft Edge version
    Launch Edge, navigate to edge://settings/help, or run 'Get-AppxPackage *MicrosoftEdge* | Select-Object Name, Version' in PowerShell
    Affected if Any version number is returned - the CVE states all Edge versions are affected
  3. Confirm Edge is the default or used browser
    Check Windows default browser settings under Settings > Apps > Default apps, or observe if Edge is actively used for web browsing
    Affected if Microsoft Edge is set as default or regularly used for browsing - this makes the SOP bypass exploitable in regular use
  4. Verify the vulnerable feature is accessible
    The vulnerability involves Edge handling of about:blank frames combined with data: URLs - check if Edge's content process allows navigation between these URL types
    Affected if Edge handles about:blank and data: URLs - the CVE indicates this specific URL combination triggers the SOP bypass

If Microsoft Edge is installed and used, the environment is affected since all versions of Edge contain this Same Origin Policy bypass vulnerability.
