CVE-2026-11778
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 · uneditedThe The CURCY – Multi Currency for WooCommerce – Smoothly on WooCommerce 9.x plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.2.14. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

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.
-
Locate the CURCY plugin directoryCheck your WordPress installation under wp-content/plugins/ for a folder named 'woo-multi-currency', 'multi-currency-for-woocommerce', or similar CURCY-related directoryAffected if The plugin directory exists in your WordPress plugins folder
-
Identify the installed versionOpen the main plugin PHP file (usually the first .php file in the plugin folder) and look for the version comment header (e.g., 'Version: x.x.x') or check the plugin header via WordPress admin under Plugins > Installed PluginsAffected if The version is 2.2.14 or below, or the version cannot be determined (assume affected)
-
Confirm the plugin is activeCheck WordPress admin under Plugins > Installed Plugins to see if CURCY - Multi Currency for WooCommerce is activated, or query the wp_options table for the option naming pattern related to this pluginAffected if The plugin is active and the version is 2.2.14 or below
-
Verify unauthenticated access to vulnerable endpointInspect the plugin code for functions that call do_shortcode with unsanitized user input (look for do_shortcode($_POST, $_GET, or similar direct superglobal usage). Test by sending a request with a harmless shortcode like [wp] to any CURCY-related AJAX or front-end endpointAffected if The plugin processes shortcode calls without validating that the input comes from authorized users or admin pages
Your environment is affected if the CURCY - Multi Currency for WooCommerce plugin is installed, active, and running at version 2.2.14 or lower, as this version allows unauthenticated arbitrary shortcode execution through improper input validation.
