CVE-2026-73224
Electerm check folder size function may get attacked by unsafe folder name
Description

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.15.120, electerm allows a malicious FTP or SFTP server to execute arbitrary commands when a user downloads a crafted folder and invokes Properties and Calculate Size because calcLocal in src/client/components/sftp/file-info-modal.jsx inserts the server-controlled folder name into a du -sh shell command without safely escaping single quotes. This issue is fixed in version 3.15.120.
