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.
-
Check installed plugin versionNavigate to WordPress admin > Plugins > Installed Plugins > Eupago Gateway Woocommerce and note the version number displayedAffected if Version displayed is 3.1.9 or lower
-
Identify state-changing forms in the pluginLocate the plugin files (typically in wp-content/plugins/eupago-gateway-for-woocommerce) and search for form definitions that perform actions like settings updates, payment processing, or user data changesAffected if Forms exist that handle sensitive operations without apparent nonce field generation
-
Inspect form HTML for nonce fieldsView page source of any plugin admin pages or frontend forms, or examine PHP form generation code for presence of wp_nonce_field, wp_nonce_url, or similar nonce creation functionsAffected if State-changing forms lack nonce input fields or nonce URLs
-
Verify server-side nonce validationExamine PHP handler files for state-changing actions (POST requests) and check if they include wp_verify_nonce, check_admin_referer, or verify_nonce_raw calls before processingAffected if POST action handlers do not validate nonces or do not verify the Referer/Origin header
User is affected if the plugin version is 3.1.9 or lower AND the plugin forms handling state-changing actions lack server-side nonce validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (nonces) on all state-changing forms and AJAX actions within the plugin, validate the nonce server-side on every POST request, and verify the Referer/Origin header to ensure requests originate from legitimate sources.
