SCA: security update for electerm (GHSA-q4p8-8j9m-8hxj)
high Tenable Self-Hosted Container Security Plugin ID 441519
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to version
3.7.9, a code execution (RCE) vulnerability exists in electerm's SFTP open with system editor or "Edit
with custom editor" feature. When a user opts to edit a file using open with system editor or open with a
custom editor, the filename is passed directly into a command line without sanitization. A malicious actor
controlling the SSH server or user OS can exploit this by crafting a filename containing shell
metacharacters. If a victim subsequently attempts to edit this file, the injected commands are executed on
their machine with the user's privileges. This could allow the attacker to run arbitrary code, install
malware, or move laterally within the network. This issue has been patched in version 3.7.9.
(CVE-2026-43943)
Solution
Update the electerm library and its related packages to version 3.7.9 or later.See Also
