New Feature: CORS for extension content scripts | Manifest V3 next phase
It's behind a flag: edge://flags/#cors-for-content-scripts CORS for content scripts Prevent content scripts of Extensions from bypassing CORS. – Mac, Windows #cors-for-content-scripts Microsoft Edge Version 83.0.477.0 (Official build) canary (64-bit) Overview When web pages request cross-origin data with fetch or XHR APIs, the response is denied unless CORS headers allow it. In contrast, extension content scripts have traditionally been able to fetch cross-origin data from any origins listed in their extension's permissions, regardless of the origin that the content script is running within. As part of a broader Extension Manifest V3 effort to improve extension security, privacy, and performance, these cross-origin requests in content scripts will soon be disallowed. Instead, content scripts will be subject to the same request rules as the page they are running within. Extension pages, such as background pages, popups, or options pages, are unaffected by this change and will continue to be allowed to bypass CORS for cross-origin requests as they do today. https://www.chromium.org/Home/chromium-security/extension-content-script-fetches
MSGraph API call blocked by "CORS policy"
I'm integrating UI Integration Cards into SAP Work Zone, and I'm trying to show data from Microsoft Outlook by calling the Microsoft Graph API. The problem now is that I need to request the /authorize and /token endpoint from the Microsoft Identity Platform to authorize the user and receive an access token to make requests to the Microsoft Graph API. But when calling either endpoint, I get the error: "Access to fetch at '(requested URL)' from origin'(my URL) has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled." I also tried calling the API with the 'no-cors' mode in the fetch function, but I got an 400 (Bad Request) response. Is there a way to surpass getting blocked by the CORS policy? Maybe with some sort of "proxy" in Azure AD or so?
