Electron 是一个使用 JavaScript、HTML 和 CSS 开发跨平台桌面应用的框架。在 42.11.9、43.7.6、44.5.0 和 45.0.0-alpha.13 版本之前，某些跨域 iframe 发出的 pointerLock 权限请求会导致 接收到顶层帧的 和 值，而非实际发起请求的 iframe 帧的对应值。因此，若应用程序嵌入了不可信的 iframe 内容，并依据请求来源（origin）授予 pointerLock 权限，则可能错误地以顶层页面的身份授予该权限。对于拒绝为不可信嵌入内容授

Vulnerability Title
Electron: Pointer lock permission requests can be attributed to the wrong frame
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 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13, pointerLock permission requests from some cross-origin iframes caused session.setPermissionRequestHandler() to receive the top-level frame's requestingUrl and isMainFrame values instead of those of the requesting frame. An application that embeds untrusted iframe content and grants pointer lock based on the requesting origin could therefore grant the permission under the top-level page's identity. Applications that deny pointerLock for untrusted embedded content are not affected. This issue is fixed in versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13.
