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
In Min before 1.31.0, local files are not correctly treated as unique security origins, which allows them to improperly request cross-origin resources. For example, a local file may request other local files through an XML document.

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

Min browser before 1.31.0 fails to properly enforce the Same-Origin Policy for local file:// URLs, treating all local files as a single origin instead of unique origins. This allows a malicious local HTML file to make XMLHttpRequest or fetch requests to other local files on the system, potentially exfiltrating sensitive data.

MitigationUpgrade Min browser to version 1.31.0 or later to obtain the fix that correctly treats each local file as a unique security origin.

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. Identify Min browser installation
    Locate the Min browser executable or application package on the system
    Affected if Min browser version 1.29.0 is installed and running
  2. Determine installed version of Min
    Check the browser version through its help menu, about dialog, or executable properties - compare against the affected version 1.29.0
    Affected if The installed version matches 1.29.0 exactly
  3. Verify local file access is enabled
    Check if the browser allows loading local files via file:// URLs or has a setting that permits local file access
    Affected if Local file loading via file:// URLs is permitted in the browser settings
  4. Test Same-Origin Policy for file URLs
    Create two test HTML files locally and attempt to make an XMLHttpRequest or fetch request from one to the other - if successful without origin errors, the vulnerability is present
    Affected if A local HTML file can successfully request content from a different local file using fetch or XMLHttpRequest, indicating the Same-Origin Policy is not properly enforced for file:// URLs

A user is affected if they have Min browser version 1.29.0 installed and use the browser to access local files via file:// URLs, allowing potential cross-file data access.

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

Upgrade Min browser to version 1.31.0 or later to obtain the fix that correctly treats each local file as a unique security origin.

Recommended fix Moderate confidence

Min 1.31.0 or later

  1. Identify the current version of Min browser installed (help/about in the application menu)
  2. Download Min version 1.31.0 or later from the official GitHub repository (github.com/minbrowser/min)
  3. Close all instances of the Min browser
  4. Install the updated version of Min, replacing the existing installation
  5. Restart Min and verify the new version is running (help/about)
  6. Test that local files are now properly treated as unique security origins
