Input validation vulnerability in Serial Codes Generator and Validator with WooCommerce Support 2.4.15

The Serial Codes Generator and Validator with WooCommerce Support plugin for WordPress is vulnerable to a security issue called Stored Cross-Site Scripting. This means that an attacker, who only needs minimal permissions like a subscriber, can inject malicious web scripts into a page. This will cause the script to execute whenever someone visits the page. This vulnerability is present in versions up to and including 2.4.14 due to a lack of proper sanitization and output escaping.
