    [+] References : https://packetstorm.news/files/id/211375/ & 	CVE-2025-9209
    
    [+] Summary : 
    
    A security weakness allows unauthorized enumeration of user metadata through
    the WordPress REST API endpoint:
    
        /wp-json/wp/v2/users?per_page=100
    
    Some installations expose sensitive metadata fields, including:
    
        _rp_api_user_private_key     (bcrypt hashes)
        _rp_api_user_public_key      (hex or large key strings)
        _rp_api_user_token_key       (JWT tokens)
    
    An attacker could harvest sensitive information if these fields are not
    properly protected.
    
    Impact
    ------
    • Leakage of private cryptographic material.  
    • Exposure of valid JWT authentication tokens.  
    • Potential privilege escalation.  
    • Unauthorized customer information access.
