Cross-Domain Misconfiguration refers to improper settings that allow unauthorized access to resources across different domains. This vulnerability can expose sensitive information and enable attacks such as Cross-Site Request Forgery (CSRF) and Cross-Site Scripting (XSS). It often occurs due to incorrect configuration of CORS (Cross-Origin Resource Sharing) policies.


To mitigate this vulnerability, restrict access by configuring the ‘Access-Control-Allow-Origin’ HTTP header to a specific set of domains or remove CORS headers altogether, enforcing the Same Origin Policy (SOP).
