Gotenberg has an unauthenticated denial of service via echo.Context pool reuse in webhook async goroutine

Summary The webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent request claims the recycled context, c.Reset clears the store. If the...
