Electron 是一个使用 JavaScript、HTML 和 CSS 开发跨平台桌面应用程序的框架。在 42.11.3、43.7.0、44.3.0 和 45.0.0-alpha.6 版本之前，Electron 将从链接打开到新窗口的页面视为由应用程序发起的导航，而非保留包含该链接的页面作为发起者。这导致顶层请求可能被错误分类为同站（same-site），从而发送 SameSite=Strict 类型的 Cookie，且 Sec-Fetch-Site 请求头无法正确标识发起页面。因此，若应用程序加载了不可信内容并

Vulnerability Title
Electron: SameSite cookie restrictions are not applied to windows opened from links
Source: CVE Program / CVE List V5
Vulnerability Description
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6, Electron treated pages opened into a new window from links as application-initiated navigations instead of preserving the page containing the link as the initiator. The resulting top-level request could be classified as same-site, causing SameSite=Strict cookies to be sent and Sec-Fetch-Site not to identify the initiating page. An application that loads untrusted content and permits it to open new windows could therefore allow that content to make a credentialed request to another site that relies on SameSite cookies for CSRF protection. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6.
