If the server denies including the resource (by not setting the Access-Control-Allow-Origin HTTP header), Means it will load the resource as if the integrity attribute was not set, effectively losing all the security SRI brings in the first place.Ĭrossorigin="anonymous" results that no credentials are sent to the cross-origin site hosting the content. Without a crossorigin attribute, the browser will choose to 'fail-open' which When the request is not on the same origin the crossorigin attribute must be present to check the integrity of the Why do I need to include crossorigin="anonymous"?
