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 WP NG Weather plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ng-weather' shortcode in all versions up to, and including, 1.0.9 due to insufficient input sanitization and output escaping on user supplied attributes. 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 WP NG Weather WordPress plugin up to version 1.0.9 contains a stored XSS vulnerability in its 'ng-weather' shortcode. Authenticated attackers with contributor-level access can inject arbitrary JavaScript through unsanitized shortcode attributes. The plugin fails to sanitize input and escape output, allowing malicious scripts to persist and execute when other users view infected pages.

MitigationUpdate the plugin to the latest version once available, or remove/disable the plugin if no patch exists. Audit all pages using the shortcode for injected malicious content and clean any identified payloads.

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 WP NG Weather plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'WP NG Weather' or 'ng-weather' in the plugin list
    Affected if The plugin appears in the installed plugins list
  2. Check installed plugin version
    Click on the plugin to view its details, or check the plugin header in wp-content/plugins/ng-weather/ng-weather.php for the 'Version' field
    Affected if Version is 1.0.9 or lower
  3. Identify pages using the ng-weather shortcode
    Search the WordPress database: SELECT * FROM wp_posts WHERE post_content LIKE '%[ng-weather%' OR use a plugin like Search Regex to scan post_content and postmeta for occurrences of [ng-weather
    Affected if Any posts or pages contain the [ng-weather] shortcode
  4. Inspect shortcode attributes for unsanitized content
    Examine the shortcode usage in post content, for example [ng-weather city="<script>alert(1)</script>"] or any attribute containing quotes, angle brackets, or javascript: patterns
    Affected if Any shortcode attribute contains raw HTML, script tags, or suspicious JavaScript patterns like <script, javascript:, onload, onerror

You are affected if the WP NG Weather plugin version is 1.0.9 or lower AND any page/post contains the [ng-weather] shortcode with unsanitized attributes in the content.
