Summary
The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting via 'order_email' in all versions up to, and including, 7.0.5 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.
Risk Assessment
An unauthenticated attacker can inject malicious scripts that execute in a user's browser, potentially leading to session theft, redirects, or other attacks. This risk affects all WordPress sites using this plugin.
Recommendation
Update the Premium Packages plugin to a version later than 7.0.5 as soon as it becomes available. Until then, consider disabling the plugin or deploying traffic filtering (WAF).
