## ps_checkout ExpressCheckout silent login account takeover (CVE-2025-61922)

> Missing identity validation in the `ps_checkout` module `< 5.0.5` lets an unauthenticated attacker **switch the session to any customer by supplying their email**.

- **Endpoint (unauth):** `POST /module/ps_checkout/ExpressCheckout`.
- **Flow:** `ExpressCheckout.php` accepts attacker JSON, only checks `orderID`, builds `ExpressCheckoutRequest` and calls `ExpressCheckoutAction::execute()`.
- **Auth bug:** In vulnerable versions `ExpressCheckoutAction` calls `CustomerAuthenticationAction::execute()` when no user is logged in. That method simply does `customerExists(<payer_email>)` and `context->updateCustomer(new Customer($id))`, so **email existence == login** (no password/token check).
- **Attacker-controlled email field:** `order.payer.email_address` inside the JSON payload is read by `ExpressCheckoutRequest::getPayerEmail()`.

### Exploitation steps

1. Collect any registered customer email (admin is separate and not affected by this flow).
2. Send an unauthenticated POST to the controller with `orderID` plus the victim email in `order.payer.email_address`.
3. Even if the endpoint returns `500`, the response will include cookies for the victim’s customer context (session already switched), enabling PII access or purchasing with saved cards.

```http
POST /module/ps_checkout/ExpressCheckout HTTP/1.1
Host: `<target>`
Content-Type: application/json
Content-Length: 72

{"orderID":"1","order":{"payer":{"email_address":"[email protected]"}}}
```
