This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 1.3%, top 32% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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:130. The runLinux() function appends attacker-controlled remote version strings directly into an exec("rm -rf ...") command without validation. This issue has been patched in version 3.3.8.
