Payload Ecommerce has an order confirmation validation issue

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.
