WP Baseline

WP Baseline is a Composer package that provides baseline functionality for WordPress. Some of the functionality includes:

• Cleanup of unnecessary WordPress features
• Enhanced security measures
• SVG upload support with sanitization
• Cleanup of the admin dashboard

Requirements

• PHP >= 8
• WordPress >= 6

Installation & Usage

This library is meant to be dropped into a theme or plugin via composer.

1. In your WordPress project directory, run: composer require builtnorth/wp-baseline.
2. In your main plugin file or theme's functions.php, add:

use WPBaseline;

if (class_exists('WPBaseline\App')) {
    $baseline = new WPBaseline\App;
    $baseline->boot();
}

Features

Disable Comments

Comments remain enabled by default. To disable them, set this filter to return true:

add_filter('wpbaseline_disable_comments', '__return_true');

Howdy Text

By default the "Howdy" text is removed from the admin bar. You can customize this and add your own text using the following filter:

add_filter('wpbaseline_howdy_text', function ($text) {
    return 'Hey,';
});

Admin Bar

By default the WP logo, search, and updates nodes are removed from the admin bar. They can be re-enabled using the following filter:

add_filter('wpbaseline_clean_admin_bar', '__return_false');

Dashboard Widgets

Most core dashboard widgets are removed. They can be re-enabled using the following filter:

add_filter('wpbaseline_remove_dashboard_widgets', '__return_false');

Emojis

Emojis are disabled. They can be re-enabled using the following filter:

add_filter('wpbaseline_disable_emojis', '__return_false');

Auto Update Emails

Auto update emails are disabled. Additionally, the from name in the email is customized based on the site name. This functionality can be reverted back to the default by using the filter:

add_filter('wpbaseline_disable_update_emails', '__return_false');

Asset Version Numbering

Wordpress adds a version query argument to all enqueued assets by default. This exposes the version number, which can be a security risk. WP Baseline replaces the version number with filemtime of the theme's style.css file by default with a fallback to date('Ymd'). However, you can set a custom version by defining a constant in your theme or plugin:

define('YOUR_THEME_VERSION', '1.2.9');
add_filter('wpbaseline_asset_version_constant', function () {
    return 'YOUR_THEME_VERSION';
});

Security Headers

WP Baseline implements security headers by default for enhanced security. These include:

• Content Security Policy (CSP)
• X-Content-Type-Options
• X-Frame-Options
• And more...

To disable all security headers:

add_filter('wpbaseline_enable_security_headers', '__return_false');

To modify specific headers or CSP rules, use these filters:

// Modify security headers
add_filter('wpbaseline_security_headers', function($headers) {
    // Customize headers
    $headers['X-Frame-Options'] = 'DENY';
    return $headers;
});

Login Security

The following items have been added to enhance login security:

• Prevent username login
• Returnsa generic login error message
• Disable autocomplete for login fields

To disable login security enhancements, use the following filter:

add_filter('wpbaseline_login_security', '__return_false');

REST API User Endpoints

REST API user endpoints are restricted to users with the list_users capability by default. To disable this restriction and make the user endpoint publicly accessible again use this filter:

add_filter('wpbaseline_disable_user_rest_endpoints', '__return_false');

XMLRPC

XMLRPC is disabled by default. To re-enable it, use the following filter:

add_filter('wpbaseline_disable_xmlrpc', '__return_false');

SVG Support

Adds support for SVG uploads. SVGs are automatically sanitized upon upload using the enshrined/svg-sanitize library for security to remove potentially malicious content.

To disable SVG support, use the following filter:

add_filter('wpbaseline_enable_svg_support', '__return_false');
