A fix was pushed into the master branch but not yet published.
Overview
org.webjars.npm:electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.
Affected versions of this package are vulnerable to Hidden Functionality via the commandLineSwitches webPreference. An attacker can inject arbitrary command-line switches into the renderer process by supplying untrusted configuration objects, potentially disabling security controls or sandboxing.
Note:
This is only exploitable if external or untrusted input is used to construct webPreferences without an explicit allowlist.
Workaround
This vulnerability can be mitigated by not spreading untrusted input into webPreferences and by using an explicit allowlist of permitted preference keys when constructing options from external configuration.
