Payload is a free and open source headless content management system. In @payloadcms/plugin-ecommerce versions before 3.90.0 and canary versions before 4.0.0-canary.34, use of the Stripe payment adapter can allow a Stripe order confirmation to be processed more than once under certain conditions. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

GHSA-8r29-2mp2-pmrw — Payload Ecommerce has an order confirmation validation issue

Affected: npm: @payloadcms/plugin-ecommerce

## Impact When using the Stripe payment adapter, an order confirmation could be processed more than once under certain conditions.

You are affected if: - You use `@payloadcms/plugin-ecommerce` with the Stripe payment adapter.

Deployments that do not use the Stripe payment flow are not affected.

## Patches Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.

## Workarounds Ensure Stripe order confirmations can only be processed once. This is a temporary mitigation; upgrading to a patched version is recommended.
