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 Out-of-bounds Read in the second-instance event handler when parsing a crafted second-instance message via the app.requestSingleInstanceLock process. An attacker can access sensitive memory contents or cause application instability by sending a specially crafted message from another process running as the same user.
Note:
This is only exploitable if the application calls app.requestSingleInstanceLock() and is running on macOS or Linux as the same user.
