Input validation vulnerability in WooCommerce Google Sheet Connector 1.3.4

The WooCommerce Google Sheet Connector plugin for WordPress has a vulnerability that could allow unauthenticated attackers to update its access code. This is possible because versions up to and including 1.3.4 did not have the necessary security measures to prevent it, such as nonce validation. To exploit this vulnerability, a site administrator would need to be tricked into performing an action, like clicking on a malicious link.
