Magento Open Source and Adobe Commerce send a “Payment Transaction Failed Reminder” email when checkout payment fails. Core Magento does not provide a switch to turn this off.

This module adds Send Payment Failed Email under Stores → Configuration → Sales → Checkout → Payment Failed Emails. When set to No, Magento skips the payment-failed email flow entirely (the email is not generated).

That control is especially useful as a containment measure related to StyleSmuggler (CVE-2026-75650), a Magento / Adobe Commerce vulnerability where remote code execution is triggered while rendering the payment-failed email template. Disabling the flow blocks that generation path.

This module is a hardening option, not a substitute for Adobe’s official hotfix (for example VULN-39341 / APSB26-146). Apply the vendor patch and use the toggle as an additional safeguard where appropriate.
