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
The CodePeople Post Map for Google Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cpm_point' Post Meta in all versions up to, and including, 1.2.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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

The CodePeople Post Map for Google Maps WordPress plugin fails to properly sanitize the 'cpm_point' post meta input and escape it during output, allowing authenticated users with Contributor-level permissions to inject malicious JavaScript that executes when other users view affected pages.

MitigationUpdate the plugin to a version beyond 1.2.6 that implements proper input sanitization using WordPress functions like sanitize_text_field() and output escaping with esc_html() or esc_attr().

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 plugin version
    In WordPress admin, go to Plugins > Installed Plugins > CodePeople Post Map for Google Maps and note the version number displayed. Alternatively, check the plugin's main PHP file (typically in wp-content/plugins/post-map-for-google-maps/) for the Version header in the plugin comment block.
    Affected if The installed version is 1.2.6 or lower.
  2. Verify plugin is active
    In WordPress admin, go to Plugins > Installed Plugins and confirm that CodePeople Post Map for Google Maps shows as 'Active'.
    Affected if The plugin is active and version is 1.2.6 or lower.
  3. Query database for cpm_point meta entries
    Run a SQL query on the WordPress database: SELECT post_id, meta_value FROM wp_postmeta WHERE meta_key = 'cpm_point'. Inspect the meta_value field for any script tags, javascript: URLs, onload/onerror attributes, or other XSS payloads.
    Affected if Any cpm_point meta values contain unescaped HTML, script tags, or JavaScript event handlers.
  4. Inspect post content for stored XSS
    View pages or posts that use the Google Maps plugin. View the page source and check if the cpm_point data appears unescaped (visible as raw HTML tags rather than escaped entities).
    Affected if The cpm_point data renders as executable JavaScript or displays raw HTML tags in the page source.

If the plugin version is 1.2.6 or lower and active, and the cpm_point meta field contains any injected script tags or unescaped HTML/JavaScript, the environment is affected by this stored XSS vulnerability.
