Vulnerability in electron (CVE-2020-15215)
Summary
Vulnerability in electron (CVE-2020-15215). Risk of unauthorized operations or information disclosure. Exploitable via contextIsolation. Mitigation: upgrade to 11.0.0-beta.6 or later.
Original description
The description as published by the source.
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.
