CloudFront verfГјgt Гјber zwei vordefinierte Richtlinien, die von der Art des verwendeten Ursprungs abhГ¤ngen: CORS-S3Origin und CORS-CustomOrigin. This name is displayed in the Fastly web interface. Access-Control-Request-Method Ursprung Um CORS entweder fГјr S3 oder einen benutzerdefinierten Ursprung zu aktivieren, mГјssen Sie die erforderlichen Header an den Ursprung Гјbertragen. To have Chrome send Access-Control-Allow-Origin in the header, just alias your localhost in your /etc/hosts file to some other domain, like: 127.0.0.

In the Name field, enter a descriptive name for the new header (e.g., CORS S3 Allow). I believe this might likely be that Chrome does not support localhost to go through the Access-Control-Allow-Origin- see Chrome issue.

Solution Unless the target application is specifically designed to serve public content to any domain, the 'Access-Control-Allow-Origin' should be configured with an allowlist including only known and trusted domains to perform cross-domain requests if needed, or should be disabled.We recommend only enabling CORS when you have sub-resources on your server that you want other origins to load, especially if you allow requesting code from any origin, as it makes things less secure. An attacker could abuse this configuration to retrieve private content from an application which does not use standard authentication mechanisms (for example, an Intranet allowing access from the internal network only). The 'Access-Control-Allow-Origin' header is insecure when set to '*' or null, as it allows any domain to perform cross-domain requests and read responses. The CORS policy allows the application to specify exceptions to the protections implemented by the browser, and enables the developer to specify allowlisted domains for which external JavaScript is permitted to execute and interact with the page. This in turn prevents malicious JavaScript being executed when loaded from external domains.

The Same Origin Policy requires that both the JavaScript and the page are loaded from the same domain in order to allow JavaScript to interact with the page. The Access-Control-Allow-Origin is a response header that is used to indicates whether the response can be shared with requesting code from the given origin. Synopsis Insecure 'Access-Control-Allow-Origin' Header Description Cross Origin Resource Sharing (CORS) is an HTML5 technology which gives modern web browsers the ability to bypass restrictions implemented by the Same Origin Policy.
