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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Welcart e-Commerce is installedCheck your WordPress plugins directory or theme folder for the Welcart plugin/theme. Look for files or directories containing 'welcart' in the name, typically found in /wp-content/plugins/ or /wp-content/themes/.Affected if The Welcart e-Commerce plugin or theme is present in the WordPress installation.
-
Identify the installed Welcart versionCheck the plugin header in welcart-main-file.php or version.php, or look in the WordPress admin under Plugins > Welcart e-Commerce to view the installed version number.Affected if The version number displayed is 2.9.3 or lower.
-
Check for unsanitized user input handlingReview custom code or Welcart template files for direct use of $_GET, $_POST, or $_REQUEST variables in SQL queries without using $wpdb->prepare() or parameterized queries. Focus on search, filter, and checkout-related form handlers.Affected if SQL queries directly incorporate user input without sanitization or prepared statements.
-
Audit database query functionsSearch Welcart core files for $wpdb->query() or $wpdb->get_results() calls and verify whether the query strings use placeholders (%s, %d) or concatenation with user-supplied variables.Affected if User-supplied values are concatenated into SQL query strings rather than being passed as bound parameters.
If Welcart e-Commerce version 2.9.3 or lower is installed AND user input is directly used in database queries without sanitization, the environment is affected by this SQL injection vulnerability.
