## Affected

- codename065 Premium Packages – Sell Digital Products Securely: through 7.2.6

## Description

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'checkout[billing][phone] (and state / taxid / email)' parameter in all versions up to, and including, 7.2.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
