CVE Catalog

CVE-2026-82215

MediumCVSS 5.9
Published: Updated: Translated: NVD NIST

Summary

The Payment Gateway PayPay for WooCommerce WordPress plugin from 0.5 to 0.9.3 does not verify the authenticity of the payment notifications it receives before acting on them. This allows unauthenticated attackers who know the store's merchant identifier to mark arbitrary orders as paid, or to cancel or fail them.

Risk Assessment

An attacker could manipulate order statuses, leading to financial losses, fraud, and disruptions in order fulfillment. This may also undermine customer trust.

Recommendation

Update the Payment Gateway PayPay for WooCommerce plugin to a version later than 0.9.3. Verify that the plugin validates the authenticity of payment notifications.
