#Permissions for php file secure code#

So far you haven’t introduced much new PHP code into the system. With just WordPress core and a theme, you have a basic site that provides the usual functionality that WordPress includes. Themes don’t usually contain much PHP code and the code complexity is low. Sites don’t change their themes often once they’ve installed them, so new vulnerabilities or bugs are not likely to be introduced into a site’s theme. In other words, there are so many people looking at WordPress core these days, it’s unlikely that someone won’t notice a bug or vulnerability, report it and take credit for it.Ī WordPress site also includes a theme which is mostly HTML, CSS and javascript and usually includes a small amount of PHP code. “Given enough eyeballs, all bugs are shallow” As Eric Raymond says in the Cathedral and the Bazaar, WordPress core’s code is inspected often by the open source community. This consists of PHP code, HTML, javascript code and CSS rules. WordPress as a publishing platform consists of WordPress core, which is the core content management system. Where and Why Vulnerabilities Appear in WordPress This introductory article will provide you with a conceptual understanding of how vulnerabilities are introduced into PHP code in general and WordPress plugins in particular. If you later decide to join the WordPress community and write your first plugin, you will be able to produce high quality secure code that will gain you friends in the community and make your code more valuable to employers and your customers. Much of the advice we provide is applicable to PHP development in general, but we do include functions and examples in these articles that are specific to WordPress development.Įven if you are not writing WordPress applications, we encourage you to read these articles because they will provide you with an excellent foundation for writing secure PHP code. The time you invest here will benefit you and users of your web applications for years to come by helping you create more secure PHP applications. We recommend you go through each article in order to build a solid foundational knowledge that you can build on as you progress. In later sections we will provide you with a few tools to help you detect vulnerabilities in your code. We will then explore types of vulnerabilities with examples. We will do this by starting with a conceptual overview of PHP security. This section of the Wordfence Learning Center is designed to help you as a beginner or advanced level developer reduce the probability that you will release a vulnerability into production. If you write enough code, you will accidentally write a vulnerability at some point in your career as a developer.
