CVE-2026-103329

MediumCVSS 5.3
Published: Updated: Translated: NVD NIST

Summary

The Super Payments WordPress plugin before version 1.43.1 does not properly verify the authenticity of incoming payment webhook notifications, as the signing key is empty by default. This allows unauthenticated attackers to forge a valid signature and mark arbitrary WooCommerce orders as paid without payment.

Risk Assessment

Attackers can mark orders as paid without actual payment, leading to financial losses and integrity breaches in the order process.

Recommendation

Update the Super Payments plugin to version 1.43.1 or later, which includes a fix for webhook signature verification.
