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 Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Manoj Kumar MK Google Directions google-distance-calculator allows DOM-Based XSS.This issue affects MK Google Directions: from n/a through <= 3.1.1.

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

DOM-based Cross-site Scripting (XSS) vulnerability in the MK Google Directions (google-distance-calculator) plugin allows remote attackers to inject malicious JavaScript through unsanitized user input that gets dynamically rendered into the page DOM without proper encoding.

MitigationIdentify and sanitize all client-side input sinks (document.write, innerHTML, eval, etc.) in the plugin; implement context-aware output encoding or use a sanitization library like DOMPurify before reflecting input into the DOM.

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 plugin installation
    Check for the 'google-distance-calculator' or 'mk-google-directions' plugin directory in wp-content/plugins/ on the WordPress server filesystem
    Affected if The plugin directory exists on the server
  2. Identify installed version
    Open the main plugin PHP file (usually named similarly to the plugin slug) and locate the version string in the plugin header comment, or check readme.txt for the 'Stable tag' version
    Affected if The reported version is 3.1.1 or lower
  3. Confirm plugin is active
    Log into WordPress admin dashboard and navigate to Plugins > Installed Plugins, or query the wp_options table for the active_plugins option to check if the plugin is enabled
    Affected if The plugin shows as active or is present in the active plugins list
  4. Check for vulnerable front-end output
    View the source of any page on the site that may use the plugin's distance calculator functionality and inspect whether user-supplied parameters (such as origin/destination inputs) are reflected in the HTML without encoding
    Affected if The plugin reflects input parameters directly into the page DOM without sanitization

A user is affected if the MK Google Directions plugin version 3.1.1 or lower is installed and active on their WordPress site, enabling the DOM-based XSS to execute when user-supplied input is processed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Identify and sanitize all client-side input sinks (document.write, innerHTML, eval, etc.) in the plugin; implement context-aware output encoding or use a sanitization library like DOMPurify before reflecting input into the DOM.
