CVE-2026-73227 PUBLISHED

electerm's RDP clipboard file download may parse unsafe file name

Assigner: GitHub_M
Reserved: 11.08.2026 Published: 11.08.2026 Updated: 11.08.2026

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.15.120, electerm allows a malicious RDP server to write attacker-controlled content outside the selected save directory because the RDP clipboard download path in src/client/components/rdp/file-transfer.js passes the server-controlled CLIPRDR filename fileInfo.name to osResolve without sanitization. This issue is fixed in version 3.15.120.
