GHSA-8r29-2mp2-pmrwPayload Ecommerce has an order confirmation validation issue2026-10-06ghsa · osvUS
## 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.
