WordPress security issue to output data from user input from theme option form

Security issues arise when you write code that open up possibilities for outsiders to access your database or otherwise compromise your installation.

The above code just reads options and content from the database and translates this into static html that will be send to the browser of the page’s visitor. There’s no code (like a form) that will allow the visitor to send information back to your server. So there are no security concerns.

(Of course there still could be vulnerabilities in other parts of your code.)
