Description
Impact
_What kind of vulnerability is it? Who is impacted?_
Command Injection vulnerabilities in electerm:
A command injection vulnerability exists in `github.com/elcterm/electerm/npm/install.js:150`. The `runMac()` function appends attacker-controlled remote `releaseInfo.name` directly into an `exec("open ...")` command without validation.
Who is impacted: Users who run `npm install -g electerm` in Mac OS. An attacker who can control the remote release metadata (version string or release name) served by the project's update server could execute arbitrary system commands, tamper local files, and escalate compromise of development/runtime assets.
