Summary

Cross-Origin-Embedder-Policy header is a response header that prevents a document from loading any cross-origin resources that don’t explicitly grant the document permission (using CORP or CORS).

Solution

Ensure that the application/web server sets the Cross-Origin-Embedder-Policy header appropriately, and that it sets the Cross-Origin-Embedder-Policy header to 'require-corp' for documents. If possible, ensure that the end user uses a standards-compliant and modern web browser that supports the Cross-Origin-Embedder-Policy header (https://caniuse.com/mdn-http_headers_cross-origin-embedder-policy).
