Name of the Vulnerable Software and Affected Versions Mortgage Calculator / Loan Calculator plugin for WordPress versions up to, and including, 1.5.20

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'mlcalc' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 1.5.20, consider disabling the mlcalc shortcode until a patch is available to prevent exploitation. Restrict access to pages that use the mlcalc shortcode to minimize the risk of arbitrary web script execution. Avoid using the mlcalc shortcode in pages until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
