Secure Your WordPress Site with WPMasterToolKit's Disable REST API Module
The WordPress REST API is a powerful tool that enables third-party applications to interact with your site. However, it exposes data that can be exploited by unauthenticated users, creating potential security risks. The module Disable REST API from WPMasterToolKit offers a simple and effective solution for disabling or restricting access to the REST API, thus strengthening your site's security.
Why disable the REST API for unauthenticated users?
The REST API allows everyone, including non-connected users, to access certain public information on your site. While this is useful in some cases, it can cause problems if you don't use this functionality, or if you wish to limit access to sensitive data. Here's why you might want to disable it:
- Protecting sensitive data : Reduce the risk of public data exposure.
- Query security : Avoid abuse through unauthenticated REST API requests.
- Performance : Reduce server load by limiting unnecessary requests.
Main features of the Disable REST API module
- Access restrictions : Disables the REST API for unauthenticated users.
- Removing traces : Removes links to the REST API in the
<head>
HTML, HTTP headers and RSD (Really Simple Discovery) endpoint. - Extended compatibility : Works with all versions of the REST API (WordPress 4.7 and earlier).
- Customized error feedback : Returns a clear error message when non-connected users attempt to access the REST API.
How does the module work?
- When the module is enabled, users who are not logged in will receive an error message when they try to use the REST API.
- REST API traces, such as links in HTTP headers and
<head>
are removed to avoid reporting its existence.
How do I use the Disable REST API module?
- Activate the : Access the WPMasterToolKit dashboard and activate the module Disable REST API.
- Automatic operation : Once activated, the module works immediately, with no further configuration required.
- Test the results: Check that users who are not logged in can no longer access REST API endpoints and that traces in HTML/HTTP headers are removed.
Use cases
- Private sites : Perfect for intranets, membership sites or any installation where non-connected users don't need to access data via the REST API.
- Increased safety : Block potential access points for attackers exploiting the REST API.
- Performance optimization : Reduce server load by limiting unauthenticated REST requests.
Technical documentation: the hooks used
The module uses several hooks to disable the REST API and remove its traces:
- Filter
rest_authentication_errors
Disables access to the REST API for non-connected users.
Example:add_filter( 'rest_authentication_errors', array( $this, 'disable_rest_api' ) );
- Filters for older versions of the REST API
Ensures compatibility with versions prior to WordPress 4.7.
Example:add_filter( 'json_enabled', '__return_false' ); add_filter( 'rest_enabled', '__return_false' );
- Actions to remove traces of the REST API
- Removes REST API links in the
<head>
HTML :remove_action( 'wp_head', 'rest_output_link_wp_head', 10 );
- Removes links from HTTP headers :
remove_action( 'template_redirect', 'rest_output_link_header', 11, 0 );
- Removes the REST API URL from the RSD endpoint:
remove_action( 'xmlrpc_rsd_apis', 'rest_output_rsd' );
- Removes REST API links in the
Our technical choices
- Universal compatibility : The module supports all versions of WordPress, ensuring that it works smoothly in any environment.
- Simplicity: Works immediately after activation, without complex configuration.
- Efficiency : Prevent information leakage via the REST API, while eliminating its traces for non-connected users.
