Theme/Plugin editors are put inside your WordPress backend to make it easier to edit/customize the look and feel of your website. These features are accessible from Appearance > Theme Editor, Plugins > Plugin Editor respectively. It provides an editor to edit the code of your themes and plugins currently installed on your website. The editor packs a nice interface and numerous features such as error detection to help you efficiently edit your theme or plugin files without having to directly access the server.
While this is an extremely useful feature for someone who makes frequent changes to the website, it can also be exploited. For example, if someone gains access to your WordPress backend, they can easily hack into your files by editing the plugin/theme files. So, if you are not making any changes to your website from the backend or want to be extra secure, you can disable these two features. You can always edit the files using an FTP program to re-enable the editor in the future.
