What is known
electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to version 3.3.8, 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. This issue has been patched in version 3.3.8.
Business impact
Successful exploitation of CVE-2026-41500, a critical vulnerability (CVSS 9.8) affecting electerm, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether electerm is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
