CVSS 3.1
5.6 mediumCVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:LCVE-2020-15215
Medium (5.6) in electronjs electron. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in electron 10.1.2, 11.0.0-beta.6, 8.5.2.
Electron before versions 11.0.0-beta.6, 10.1.2, 9.3.1 or 8.5.2 is vulnerable to a context isolation bypass. Apps using both `contextIsolation` and `sandbox: true` are affected. Apps using both `contextIsolation` and `nodeIntegrationInSubFrames: true` are affected. This is a context isolation bypass, meaning that code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions.
