+## 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":"victim@example.com"}}}
+```
