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 Seo Monster plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.3.3. This is due to missing or incorrect nonce validation on the check_integration() function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request 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 Seo Monster WordPress plugin versions up to 3.3.3 contain a Cross-Site Request Forgery vulnerability in the check_integration() function due to missing or incorrect nonce validation. This allows unauthenticated attackers to forge administrative requests that can modify plugin settings and inject malicious web scripts, provided they can socially engineer a site administrator into clicking a malicious link.

MitigationUpdate the Seo Monster plugin to a version beyond 3.3.3 once a patched release is available. Until then, implement proper nonce validation on the check_integration() function and advise administrators to avoid clicking untrusted links.

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 Seo Monster plugin is installed
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins and look for 'Seo Monster' in the list, or check the /wp-content/plugins/ directory for a seo-monster folder
    Affected if Seo Monster plugin is present in the WordPress installation
  2. Identify the installed Seo Monster version
    In WordPress admin, go to Plugins > Installed Plugins > Seo Monster and read the version number displayed below the plugin name, or open the main plugin file (seo-monster.php) and locate the 'Version' header in the plugin comments
    Affected if The version number is 3.3.3 or lower
  3. Verify the check_integration function is exposed
    Access the WordPress site via GET or POST request to the endpoint that calls check_integration() - typically involves a form submission or AJAX call to the plugin's admin URL. Common paths include admin-post.php with plugin-specific parameters, or checking the plugin's PHP files for function definitions and their usage in action hooks
    Affected if The check_integration() function is defined and hooked to an accessible WordPress action without nonce validation protection
  4. Confirm missing nonce validation in the function
    Review the seo-monster plugin PHP files, specifically the check_integration() function and any associated form handlers or AJAX endpoints. Look for wp_verify_nonce() or check_admin_referer() calls within the function and its calling context
    Affected if No nonce verification is performed before executing the check_integration() logic

You are affected if Seo Monster plugin versions 3.3.3 or lower are installed and the check_integration() function handles requests without CSRF protection.

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

Update the Seo Monster plugin to a version beyond 3.3.3 once a patched release is available. Until then, implement proper nonce validation on the check_integration() function and advise administrators to avoid clicking untrusted links.

Recommended fix Moderate confidence

Version 3.3.4 or later (latest available version from wordpress.org/plugins/seo-monster/)

  1. Update the Seo Monster plugin to the latest available version from the WordPress plugin repository
  2. Navigate to Plugins > Installed Plugins in WordPress admin
  3. Locate Seo Monster and click Update Now if an update is available
  4. After updating, verify the check_integration() function now includes proper nonce validation by reviewing plugin changelog or code
  5. Confirm the site still functions correctly after the update
