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
Unrestricted Upload of File with Dangerous Type vulnerability in RomanCode MapSVG mapsvg-lite-interactive-vector-maps allows Upload a Web Shell to a Web Server.This issue affects MapSVG: from n/a through <= 8.6.4.

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

Unrestricted file upload vulnerability in MapSVG plugin versions <= 8.6.4 allows attackers to upload malicious files (web shells) directly to the web server without proper validation of file types or content, leading to potential remote code execution and complete system compromise.

MitigationUpgrade to a patched version of MapSVG immediately. If no patch is available, disable the plugin or implement server-side file type validation with whitelisting, disable script execution in upload directories, and restrict upload functionality until a fix is available.

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 MapSVG plugin is installed
    Check your WordPress or CMS plugin directory for the MapSVG plugin, or check your site's plugin list if using a CMS. Also check for any web applications that include MapSVG functionality.
    Affected if MapSVG plugin is present on the system
  2. Determine installed MapSVG version
    Locate the plugin version file (typically version.php, readme.txt, or plugin header in the main PHP file) within the MapSVG plugin directory. Compare the version number against 8.6.4.
    Affected if Installed version is 8.6.4 or lower
  3. Verify upload functionality is web-accessible
    Check if the MapSVG file upload endpoint is exposed on your web server. This typically involves checking for upload-related routes or forms provided by the plugin that accept file uploads from unauthenticated or low-privilege users.
    Affected if File upload functionality is accessible without proper authentication or validation controls
  4. Inspect upload directories for suspicious files
    Search MapSVG default or configured upload directories for unexpected file extensions (e.g., .php, .phtml, .exe, .js) that do not match expected SVG or image file types. Check file modification timestamps for recent unusual uploads.
    Affected if Unusual or executable file types are found in upload directories, especially .php or .phtml files
  5. Review web server access logs
    Examine web server access logs (Apache, Nginx, or equivalent) for POST requests to MapSVG upload endpoints, looking for requests uploading files with non-image extensions or anomalous content patterns.
    Affected if Logs show file upload requests with unexpected file types or suspicious content to MapSVG endpoints

You are affected if MapSVG plugin version 8.6.4 or lower is installed and its file upload feature is accessible on your web server.

Mitigation

Upgrade to a patched version of MapSVG immediately. If no patch is available, disable the plugin or implement server-side file type validation with whitelisting, disable script execution in upload directories, and restrict upload functionality until a fix is available.
