Finding

The skill describes outbound REST/Web Service access to PrestaShop and references sensitive material such as API keys, but it does not declare corresponding permissions. Undeclared network and environment capabilities reduce transparency and can bypass expected review or runtime policy controls, increasing the risk of unauthorized external access or secret handling.
