NewCVE-2026-43940 (opens in a new tab)How to fix?
Upgrade electerm to version 3.7.16 or higher.
Overview
electerm is an open-sourced terminal/ssh/telnet/serialport/sftp client
Affected versions of this package are vulnerable to Unsafe Dependency Resolution via the runWidget function. An attacker can achieve arbitrary code execution by supplying crafted input that exploits path traversal to load and execute malicious JavaScript files from the filesystem through the renderer process. This is only exploitable if an attacker is able to execute JavaScript in the renderer process, such as through a malicious plugin or a cross-site scripting flaw in the embedded webview.
Workaround
This vulnerability can be mitigated by avoiding the installation or execution of untrusted plugins, refraining from loading arbitrary web content in the embedded webview, and running the application in a sandboxed environment to limit the impact of code execution.
