Joomla Extension – j2commerce.com – Unescaped request data reflected into PayPal notify redirect in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 – A crafted link to the paypal notify endpoint, if followed by a victim’s browser (or an automated system that fetches it), causes the resulting redirect to `com_j2store`’s checkout controller to carry attacker-chosen query parameters instead of only the intended `view=checkout&task=confirmPayment&orderpayment_type=…&paction=process` set \u2014 parameter injection\/smuggling into that follow-up request.
