Go to dashboardElectron windows opened from links in a page are treated as same-site with the app, so SameSite=Strict cookies get sent on the request. A malicious page in the app can use this to make credentialed top-level requests to other sites that rely on SameSite cookies for CSRF protection.

Check whether the app loads untrusted content and whether its window open handler (setWindowOpenHandler) returns deny for untrusted windows.
45.0.0-alpha.6, 44.3.0, 43.7.0, or 42.11.3, matching your major linedeny } from setWindowOpenHandler for windows opened by untrusted contentEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
Pages opened into a new window from a link were loaded as if the app itself had navigated there rather than the page that contained the link, so the request was treated as same-site: SameSite=Strict cookies were sent and Sec-Fetch-Site did not identify the initiating page. Content shown in the app could use this to make a credentialed top-level request to another site that relies on SameSite cookies as a CSRF defence.
Apps are only affected if they load untrusted content and allow it to open new windows. Apps that deny new windows from untrusted content with setWindowOpenHandler are not affected.
Return { action: 'deny' } from setWindowOpenHandler for windows opened by untrusted content.
