QID 980372: Nodejs (npm) Security Update for electron (GHSA-mpjm-v997-c4h4)

Security update has been released for electron to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

This vulnerability allows a sandboxed renderer to request a "thumbnail" image of an arbitrary file on the user's system. The thumbnail can potentially include significant parts of the original file, including textual data in many cases.

All current stable versions of Electron are affected.

CVSS V3 rated as Critical - 8.6 severity.

CVSS V2 rated as Medium - 5 severity.

Solution

This was fixed with #30728, and the following Electron versions contain the fix:

- 15.0.0-alpha.10
- 14.0.0
- 13.3.0
- 12.1.0
- 11.5.0Workaround:
If your app enables `contextIsolation`, this vulnerability is significantly more difficult for an attacker to exploit.

Further, if your app does not depend on the `createThumbnailFromPath` API, then you can simply disable the functionality. In the main process, before the 'ready' event:
```js
delete require('electron').nativeImage.createThumbnailFromPath
```
