CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-4075 – Arbitrary file read via window-open IPC in Electron
https://notcve.org/view.php?id=CVE-2020-4075
In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, arbitrary local file read is possible by defining unsafe window options on a child window opened via window.open. As a workaround, ensure you are calling `event.preventDefault()` on all new-window events where the `url` or `options` is not something you expect. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4. En Electron antes de las versiones 7.2.4, 8.2.4 y 9.0.0-beta21, una lectura arbitraria de archivos locales es posible al definir opciones de ventana no seguras en una ventana secundaria abierta por medio de window.open. Como solución alternativa, asegúrense de llamar a la función "event.preventDefault()" en todos los eventos de ventanas nuevas donde la "url" u "options" no es algo que se espera. • https://github.com/electron/electron/security/advisories/GHSA-f9mq-jph6-9mhm https://www.electronjs.org/releases/stable?page=3#release-notes-for-v824 • CWE-552: Files or Directories Accessible to External Parties •
CVSS: 9.0EPSS: 0%CPEs: 23EXPL: 0CVE-2020-4076 – Context isolation bypass via leaked cross-context objects in Electron
https://notcve.org/view.php?id=CVE-2020-4076
In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, there is a context isolation bypass. Code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions. Apps using contextIsolation are affected. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4. En Electron antes de las versiones 7.2.4, 8.2.4 y 9.0.0-beta21, se presenta una omisión de aislamiento de contexto. • https://github.com/electron/electron/security/advisories/GHSA-m93v-9qjc-3g79 https://www.electronjs.org/releases/stable?page=3#release-notes-for-v824 • CWE-501: Trust Boundary Violation •
