How to Fix CVE-2026-41500

To remediate this vulnerability, upgrade all affected electerm dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

electerm fixed: 3.3.8 
npm install electerm@3.3.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls electerm

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-41500, inspect your project dependencies using npm:

npm ls electerm

Analyze the terminal output to locate any version of electerm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.8), your application is affected.

Note: The npm ls electerm command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In electerm, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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)
