Other vulnerabilities in Robokassa payment gateway for WooCommerce
See all- CVE-2026-91076Medium
The Robokassa payment gateway for Woocommerce WordPress plugin before 1.9.0 does not verify the authenticity of an incoming payment-notification request before acting on the order named in it. This allows unauthenticated attackers to force any WooCommerce order into a failed state. Order identifiers are sequential, so every order in the shop can be taken out of the fulfilment queue one request at a time.
- CVE-2026-91017Low
The Robokassa payment gateway for WooCommerce WordPress plugin before 1.8.9 does not verify the authenticity of incoming payment notifications when its non-default deferred-payment feature is enabled. This allows unauthenticated attackers to forge a notification and mark arbitrary WooCommerce orders as paid or on-hold without payment or a valid signature.
