Input validation vulnerability in Loan Calculator 1.3

The Loan Calculator tool for WordPress has a security flaw that could allow attackers to manipulate the settings and inject harmful code onto a website. This issue affects all versions of the tool up to and including 1.3. It happens because the tool does not properly check for a special code that verifies the authenticity of a request. This means that someone without proper authorization could make changes to the tool and potentially harm the website. To avoid this, site administrators should be cautious when clicking on links from unknown sources.
