Input validation vulnerability in CoinPayments.net Payment Gateway for WooCommerce 1.0.17

The plugin used to process payments on WordPress websites, CoinPayments.net Payment Gateway for WooCommerce, has a security vulnerability. This means that hackers can inject malicious code through a specific input, and potentially gain access to sensitive information or control over the website. This issue affects versions up to and including 1.0.17 and can be exploited by anyone, even without authentication. There is currently no known solution for this problem, but if there is another plugin or theme installed on the website that has its own vulnerability, the attacker could take advantage of it to perform more harmful actions.
