Ensuring your WordPress site is secure is crucial, especially when it comes to the JSON API, which can be a gateway to sensitive information if left unprotected. Here are some steps you can take to verify your site’s JSON API security:

Step 1: Directly Access API Endpoints

The first step is to try accessing your API endpoints directly. For example, you can enter the following URL in your browser:


This endpoint fetches a list of posts from your site. If this data is accessible without any authentication, it indicates a potential security concern, especially if sensitive data is exposed.

Step 2: Check Authentication Requirements

Next, ensure that authentication is required for accessing non-public data. WordPress’s REST API should generally protect sensitive information by requiring user authentication. You can test this by trying to access endpoints that should be private, such as user information or unpublished posts. If these endpoints are accessible without proper authentication, you need to adjust your settings or implement additional security measures.

Step 3: Review WordPress Settings and Security Plugins

WordPress settings and security plugins play a significant role in protecting your site’s API. Here are some actions you can take:

  • Update WordPress: Ensure your WordPress installation is up to date. Updates often include security patches.
  • Configure REST API Settings: Some plugins allow you to manage REST API access. For example, the 「Disable REST API」 plugin can restrict access to authenticated users only.
  • Use Security Plugins: Plugins like Wordfence, Sucuri, or iThemes Security offer comprehensive security features. These plugins can help you monitor API access and block unauthorized attempts.

Step 4: Use a Security Scanning Tool

Finally, employ a security scanning tool to assess your site’s API vulnerabilities. Tools like WPScan, Sucuri SiteCheck, or specialized API security scanners can identify potential weaknesses and suggest improvements. Regular scans can help you stay ahead of new threats and ensure ongoing protection.


By following these steps, you can significantly enhance the security of your WordPress site’s JSON API. Regularly checking API access, enforcing authentication, reviewing settings, and using security tools will help safeguard your data and maintain your site’s integrity. Stay vigilant and proactive to keep your WordPress site secure.
