High CVSS 8.1
CVE-2026-73223
NVD analysis in progress
electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.15.120, electerm allows a malicious SFTP server to write attacker-controlled content outside the temporary directory because the server-controlled filename name used by editWithSystemEditor in src/client/components/sftp/file-item.jsx is interpolated into path.resolve without sanitization. This issue is fixed in version 3.15.120.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can modify or destroy data and take the service offline.
- Weakness
- An attacker-supplied file path is not confined, letting them read or write outside the intended folder.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
