Cors Mitigations

Cross-Origin Resource Sharing (CORS) lets users access other domains’ resources while protecting your organization from unexpected cross-origin network access.

For Chromium browser and devices running FydeOS version 79 and later, the new CORS implementation, Out-Of-Renderer CORS, carries out CORS inspections on network requests, including Chromium extensions. Out-Of-Renderer CORS is more strict and secure than previous CORS implementations. For example, modified request HTTP headers that were previously ignored by the CORS protocol are inspected by the Out-Of-Renderer CORS protocol.

To make Chromium extensions and specific HTTP headers exempt from CORS inspection, select Enable mitigations.
