AI Agent Skill: Secure WordPress AJAX with Claude

The "Secure WordPress AJAX with Claude" skill supports developers by ensuring the secure handling of AJAX requests through WordPress's admin-ajax.php endpoint. This skill helps verify nonces, checks user capabilities, sanitizes input fields, and ensures secure responses with JSON, thereby preventing potential vulnerabilities like CSRF and injection attacks.

What this skill does

• Verifies nonces using check_ajax_referer.
• Gates actions using current_user_can to ensure only authorized users can execute certain actions.
• Unslashes and sanitizes every field to maintain input integrity.
• Returns responses with wp_send_json_success or wp_send_json_error.
• Mitigates risks such as CSRF, broken access control, and injection on the AJAX surface.

Who it is for

This skill is beneficial for WordPress developers, security-conscious development teams, and those integrating AI coding agents like Claude Code, Cursor, or Codex who require secure handling of AJAX requests in their plugins or themes.

Use cases

• Securing AJAX requests that deal with state-changing operations or sensitive data.
• Implementing AJAX handlers that interact with administrative features for logged-in users.
• Handling public AJAX actions that require careful verification and sanitization.

Technical details

• Focuses on AJAX actions registered via add_action('wp_ajax_{action}') for authenticated users.
• Handles non-privileged AJAX actions through add_action('wp_ajax_nopriv_{action}'), with caution to avoid misuse for admin tasks.
• Integrates with JavaScript methods like wp.apiFetch and fetch for requests to admin_url('admin-ajax.php').
