CVE-2026-41500

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. --- ### Patches _Has the problem been patched? What versions should users upgrade to?_ Fixed in [59708b38c8a52f5db59d7d4eff98e31d573128ee](https://github.com/electerm/electerm/commit/59708b38c8a52f5db59d7d4eff98e31d573128ee), user no need to upgrade, the new version already published in npm --- ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ no --- ### References _Are there any links users can visit to find out more?_ [59708b38c8a52f5db59d7d4eff98e31d573128ee](https://github.com/electerm/electerm/commit/59708b38c8a52f5db59d7d4eff98e31d573128ee)
