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
Unauthenticated SQL Injection in JetSmartFilters <= 3.8.3 versions.

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

Unauthenticated SQL injection vulnerability in JetSmartFilters WordPress plugin versions 3.8.3 and below allows remote attackers to inject malicious SQL queries via unsanitized input parameters without requiring any authentication credentials.

MitigationUpgrade JetSmartFilters to the latest version beyond 3.8.3. If no patched version is available, disable the plugin or implement a WAF rule to block SQL injection attack patterns until a fix is released.

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 JetSmartFilters plugin is installed
    Check the WordPress plugins directory for the jet-smart-filters folder: look in wp-content/plugins/ for a folder named jet-smart-filters or check via WP admin under Plugins > Installed Plugins
    Affected if The jet-smart-filters folder does not exist in the plugins directory
  2. Identify the installed version
    Open the main plugin file (typically jet-smart-filters.php) or the readme.txt file in the plugin folder and locate the version declaration header
    Affected if The version number found is 3.8.3 or lower, or if no version can be determined and the plugin is present
  3. Confirm the plugin is active
    Check WordPress database in wp_options table for option_name 'active_plugins', or view the Plugins page in WordPress admin dashboard
    Affected if JetSmartFilters appears in the list of active plugins and is enabled on the site
  4. Identify exposed filter endpoints
    Review plugin source code for filter AJAX handlers or public-facing endpoints (look for wp_ajax_ and wp_ajax_nopriv_ hooks in the plugin PHP files)
    Affected if The plugin registers AJAX or public endpoints that handle user-supplied parameters without authentication requirement
  5. Check for unsanitized parameter usage
    Search plugin PHP files for direct use of $_GET, $_POST, or $_REQUEST variables in SQL queries without prepare() or sanitization functions
    Affected if Code review reveals SQL queries built using unsanitized user input from request parameters

The site is affected if JetSmartFilters plugin is installed, active, and running version 3.8.3 or below with publicly accessible filter endpoints that process SQL queries via unsanitized input parameters.

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

Upgrade JetSmartFilters to the latest version beyond 3.8.3. If no patched version is available, disable the plugin or implement a WAF rule to block SQL injection attack patterns until a fix is released.

Recommended fix Moderate confidence

Latest available version of JetSmartFilters (newer than 3.8.3)

  1. Check the current version of JetSmartFilters plugin installed on your WordPress site
  2. Navigate to Plugins > Installed Plugins in WordPress admin
  3. If JetSmartFilters version is 3.8.3 or lower, update to the latest available version from the WordPress plugin repository
  4. After updating, verify the new version number in the Plugins list
  5. Test critical filter functionality on the frontend to ensure the update did not break existing features
  6. Check JetSmartFilters changelog or Crocoblock official channels for specific version containing the security fix
Caveat Review plugin changelog for any backward-incompatible changes before updating in production environments
