CVE-2026-93654: Premium Packages <= 7.2.1 - Unauthenticated Stored Cross-Site Scripting via 'cart_items[][product_name]' Parameter
The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cartitems[][productname]' Parameter in all versions up to, and including, 7.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The checkout REST route uses permissioncallback set to returntrue and the invoice loader performs no order ownership check, meaning an unauthenticated attacker can both persist the payload and ensure it is renderable to any logged-in user who accesses the invoice.

Frequently Asked Questions
Who can exploit this issue?
An unauthenticated remote attacker can exploit it. The checkout REST route allows access through a permission callback that always returns true, and the invoice loader does not verify order ownership.
What user interaction is required for the injected script to run?
The attacker can store a script payload in the product_name field of cart items. The script executes when a logged-in user accesses the affected invoice page.
Are installations running version 7.2.1 affected?
Yes. The issue affects all versions up to and including 7.2.1.
