## Technical details

A stored cross-site scripting (XSS) vulnerability exists in the WordPress Stripe Payments plugin version 2.0.39 and below. The flaw is located in the 'currency_code' parameter within the 'AcceptStripePayments-settings' group. An authenticated attacker with sufficient privileges to modify plugin options can submit a crafted POST request to /wp-admin/options.php containing a malicious JavaScript payload. Because the input is not properly sanitized before being stored and subsequently rendered in the administrative settings page, the script executes in the context of any administrator who views the plugin's configuration. This can lead to session hijacking or unauthorized administrative actions.
