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 SmartCrawl WordPress SEO checker, SEO analyzer, SEO optimizer plugin for WordPress is vulnerable to unauthorized ld+json description injection due to a missing capability check on the save_settings function in all versions up to, and including, 3.10.2. This makes it possible for unauthenticated attackers to save schema types.

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 SmartCrawl WordPress plugin fails to enforce authorization checks on its save_settings AJAX function, allowing any unauthenticated visitor to inject or modify ld+json schema data. This broken access control vulnerability permits schema poisoning for SEO manipulation or potentially XSS injection through malicious schema markup.

MitigationUpdate SmartCrawl plugin to version 3.10.3 or later which includes proper capability validation on the save_settings function. If immediate update is not possible, disable the plugin or restrict access to the vulnerable endpoint via web server configuration.

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 SmartCrawl plugin installation and version
    Navigate to WordPress Admin > Plugins and locate SmartCrawl, or inspect the plugin main file (usually in wp-content/plugins/smartcrawl-seo/) and read the version header comment
    Affected if SmartCrawl is installed with a version lower than 3.10.3
  2. Confirm ld+json schema feature is in use
    Go to SmartCrawl settings > Schema (or SEO > Schema) and check if any schema markup is configured or enabled
    Affected if Schema/ld+json configuration exists and the plugin is active
  3. Verify AJAX endpoint accessibility
    Check if the WordPress AJAX endpoint /wp-admin/admin-ajax.php is exposed without authentication, and confirm the save_settings action is callable by inspecting plugin JavaScript files or making a test POST request to admin-ajax.php with action=smartcrawl_save_settings
    Affected if The AJAX endpoint responds without requiring authentication and accepts the save_settings action
  4. Inspect current schema markup in page source
    View the source of a published page on the site and search for <script type="application/ld+json"> tags to see current schema data
    Affected if Schema markup is present and could have been injected or modified without authorization

A site is affected if SmartCrawl plugin version is below 3.10.3 and the ld+json schema feature is enabled, allowing unauthenticated access to modify SEO markup.
