“Cross-Origin-Resource-Policy” response header allows http servers to ask the browser to prevent cross-origin or cross-site embedding of the returned resource. It is complementary to the Cross-Origin Read Blocking feature and is especially valuable for resources not covered by CORB (which only protects HTML, XML and JSON). “Cross-Origin-Resource-Policy” is currently the only way to protect images against Spectre attacks or against compromised renderers.
