Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Arbitrary file read via window-open IPC in Electron

Impact

The vulnerability allows arbitrary local file read by defining unsafe window options on a child window opened via window.open.

Workarounds

Ensure you are calling event.preventDefault() on all new-window events where the url or options is not something you expect.

Fixed Versions

• 9.0.0-beta.21
• 8.2.4
• 7.2.4

Context isolation bypass via contextBridge in Electron

Impact

Apps using both contextIsolation and contextBridge 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.

Workarounds

There are no app-side workarounds, you must update your Electron version to be protected.

Fixed Versions

• 9.0.0-beta.21
• 8.2.4

IPC messages delivered to the wrong frame in Electron

Impact

IPC messages sent from the main process to a subframe in the renderer process, through webContents.sendToFrame, event.reply or when using the remote module, can in some cases be delivered to the wrong frame.

If your app does ANY of the following, then it is impacted by this issue:

• Uses remote
• Calls webContents.sendToFrame
• Calls event.reply in an IPC message handler

Patches

This has been fixed in the following versions:

• 9.4.0
• 10.2.0
• 11.1.0
• 12.0.0-beta.9

Workarounds

There are no workarounds for this issue.

Arbitrary Code Execution A vulnerability in Chromium, which Electron is based on, can be exploited and used to execute arbitrary code. According to the Electron team, "this affects any Electron application that may run third-party or untrusted JavaScript." Depending on the Electron application's privileges, this can allow an attacker to create and delete files or modify a user's system in other ways. Google has received reports of this vulnerability being exploited in the wild.

Affected versions: <2.0.18 || <3.0.16 || <3.1.6 || <4.0.8 || <5.0.0-beta.5
