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 Alfie – Feed Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'naam' parameter in all versions up to, and including, 1.2.1. This is due to missing nonce validation on the alfie_option_page() function combined with insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject malicious web scripts that will be stored in the plugin's database and execute whenever a user accesses the page displaying the injected data, granted they can trick a site administrator into performing an action such as clicking on a link.

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 Alfie – Feed Plugin for WordPress (versions up to 1.2.1) contains a stored XSS vulnerability in the alfie_option_page() function. The 'naam' parameter lacks proper input sanitization while being stored in the database, and output is not escaped when rendered. Combined with missing nonce validation (CSRF), this allows unauthenticated attackers to inject malicious JavaScript that executes when administrators view the affected admin page.

MitigationUpdate the plugin to version 1.2.2 or later, which should add nonce validation to the alfie_option_page() function, implement proper input sanitization for the 'naam' parameter, and ensure output escaping when displaying the data.

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. Confirm plugin installation and version
    In WordPress admin, go to Plugins > Instored Plugins and check if 'Alfie - Feed Plugin for WordPress' is listed. Note the installed version number displayed alongside the plugin name.
    Affected if The plugin is installed and the version number is 1.2.1 or lower.
  2. Locate the vulnerable settings function
    Access the plugin settings page where alfie_option_page() is invoked. This is typically found under Settings or a dedicated 'Alfie' menu item in the WordPress admin sidebar.
    Affected if The plugin settings page exists and is accessible, indicating the vulnerable function is present in the codebase.
  3. Inspect the database for stored 'naam' parameter values
    Query the WordPress options table (typically wp_options) for option names related to the plugin, looking for entries that store the 'naam' parameter value. Use: SELECT * FROM wp_options WHERE option_name LIKE '%alfie%' OR option_name LIKE '%naam%';
    Affected if Any option records exist that contain unsanitized script tags (<script>) or HTML event attributes in the 'naam' field values, indicating exploitation.
  4. Check admin page source for unescaped output
    View the plugin admin page source (or inspect element) and search for occurrences of the 'naam' parameter value. Look for unescaped characters like < > " that should have been converted to HTML entities.
    Affected if The displayed 'naam' value contains raw HTML or JavaScript without escaping, confirming the XSS vulnerability is present and exploitable.

A user is affected if the Alfie - Feed Plugin for WordPress is installed with version 1.2.1 or lower, the plugin settings page is accessible, and either malicious 'naam' parameter values exist in the database or unescaped output is rendered on the admin page.

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

Update the plugin to version 1.2.2 or later, which should add nonce validation to the alfie_option_page() function, implement proper input sanitization for the 'naam' parameter, and ensure output escaping when displaying the data.

Recommended fix Moderate confidence

Version 1.2.2 or later (check WordPress plugin repository for latest fixed release)

  1. 1. Navigate to the WordPress admin dashboard and go to Plugins > Installed Plugins
  2. 2. Locate the 'Alfie – Feed Plugin' in the list of installed plugins
  3. 3. Check if an update is available for the plugin. If an update to version 1.2.2 or higher is available, update the plugin
  4. 4. If no update is available through the WordPress admin, visit the WordPress plugin repository page for Alfie – Feed Plugin and download the latest version
  5. 5. Deactivate and delete the current version, then upload and install the new version
  6. 6. After updating, verify the 'naam' parameter is now properly sanitized and escaped in the plugin settings
