Is Payment Gateway of Stripe for WooCommerce safe? Known vulnerabilities and latest version

The Payment Gateway of Stripe for WooCommerce plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in all versions up to, and including, 5.0.8. This is due to the publicly accessible `woocommerce_api_wt_stripe` webhook endpoint (`EH_Stripe_Webhook_Handler::handle()`) wrapping the only call to `\Stripe\Webhook::constructEvent()` inside an `if (!empty($endpoint_secret))` guard that is never entered on default installations — because the `eh_stripe_webhook_secret` option is empty after a fresh plugin install — causing the raw, attacker-controlled POST body to be decoded and processed as a fully trusted Stripe event without any signature verification, authentication, or authorization. This makes it possible for unauthenticated attackers to send forged Stripe webhook events to manipulate WooCommerce order statuses, including marking unpaid orders as paid or completed via `payment_complete()`, forcing legitimate orders into a failed state, fabricating dispute notifications, and injecting forged refund events. This vulnerability is only exploitable when the Stripe webhook signing secret has not been configured by an administrator; once a valid signing secret is saved, `\Stripe\Webhook::constructEvent()` is enforced and forged requests are rejected.

Authentication Bypass Using an Alternate Path or Channel vulnerability in ThemeHigh Stripe Payment Gateway for WooCommerce allows Password Recovery Exploitation. This issue affects Stripe Payment Gateway for WooCommerce: from n/a through 5.0.7.

The Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 3.7.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.7.7. This is due to insufficient verification on the user being supplied during a Stripe checkout through the plugin. This allows unauthenticated attackers to log in as users who have orders, who are typically customers.
