GHSA-w222-53c6-c86p
Remote Code Execution in electron
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
Affected versions of `electron` may be susceptible to a remote code execution flaw when certain conditions are met:
1. The electron application is running on Windows.
2. The electron application registers as the default handler for a protocol, such as `nodeapp://`.
This vulnerability is caused by a failure to sanitize additional arguments to chromium in the command line handler for Electron.
MacOS and Linux are not vulnerable.
## Recommendation
Update electron to a version that is not vulnerable. If updating is not possible, the electron team has provided the following guidance:
If for some reason you are unable to upgrade your Electron version, you can append `--` as the last argument when calling `app.setAsDefaultProtocolClient`, which prevents Chromium from parsing further options. The double dash `--` signifies the end of command options, after which only positional parameters are accepted.
```
app.setAsDefaultProtocolClient(protocol, process.execPath, [
'--your-switches-here',
'--'
])
```
