Mapping between HTML5 and JavaScript features and Content Security Policy controls. If the Content-Security-Policy header is present in the server response, a compliant client enforces the declarative allowlist policy. One example goal of a policy is a stricter execution mode for JavaScript in order to prevent certain cross-site scripting attacks.
The same-origin policy does not prevent the browser from making GET, POST, OPTIONS, and TRACE requests; it only prevents the responses from being read by user code. Therefore, if an endpoint uses a one of these "safe" request methods to write information or perform an action on a user's behalf, it can be exploited by attackers.
Note that in the CORS architecture, the Access-Control-Allow-Origin header is being set by the external web service (service.example.com), not the original web application server (www.example.com). Here, service.example.com uses CORS to permit the browser to authorize www.example.com to make requests to service.example.com .
