Sep 8, 2026electerm before 5.3.15 exposes 40+ main-process functions through an unvalidated Electron IPC handler with no function-name allowlist or sender validation.CVE-2026-86711 · Other software · electerm · reported by VulnCheckHigh 7.5
electerm before 5.3.15 exposes 40+ main-process functions through an unvalidated Electron IPC handler with no function-name allowlist or sender validation. Renderer-side script execution can invoke openFileWithEditor and other functions with arbitrary arguments to execute system commands in the main process.

Aug 19, 2026electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client.CVE-2026-49255 · Other software · electerm · reported by GitHubHigh 8.8
electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.11.11, electerm constructs operating system commands in src/app/lib/fs.js by interpolating untrusted file paths into the rmrf(), mv(), and cp() functions. A malicious SSH or SFTP server can provide a filename containing quote characters and shell metacharacters, and a victim can cause that filename to reach the affected operation during remote-to-local transfer, conflict renaming, copying, moving, or removal. The generated `rm -rf`, mv, `cp -r`, PowerShell Remove-Item, Move-Item, or Copy-Item command can then interpret the filename as shell syntax. This allows arbitrary command execution with the electerm desktop user's privileges on POSIX and Windows systems, enabling data exfiltration, file modification, malware installation, or denial of service. This issue is fixed in version 3.11.11.

Aug 19, 2026electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client.CVE-2026-49253 · Other software · electerm · reported by GitHubHigh 7.1
electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.11.11, electerm uses remote-supplied filenames directly with path.join() while receiving Zmodem and Trzsz transfers. In src/app/server/zmodem.js, prepareReceiveFile() joins the filename to the user-selected save path, and in src/app/server/trzsz.js, getUniqueFilePath(), the openSaveFile() callback, and the savedFilePaths mapping construct destinations without sanitization. A malicious SSH server or remote shell can provide a filename containing traversal components such as ../escaped.txt or ../../.bashrc. When the victim accepts the transfer and selects a download directory, electerm can write outside that directory and overwrite files accessible to the desktop user, potentially changing sensitive configuration or impairing availability. This issue is fixed in version 3.11.11.

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.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.15.186, electerm allows an authenticated WebSocket client to invoke unintended internal functions through client-controlled func values in upgrade-func in src/app/server/dispatch-center.js and handleFs in src/app/server/fs.js, exposing Upgrade and fsExport methods that can execute commands, open files, mutate the filesystem, or terminate the process. This issue is fixed in version 3.15.186.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alter config/bookmarks. This vulnerability is fixed in 3.9.5.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. In 3.8.8 and earlier, there is persistent local-pty code execution via imported bookmarks or compromised sync targets.

The attacker can inject exec* fields or global config to cause remote code to run when a bookmark is opened or when sync is applied.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. From versions 3.0.6 to before 3.8.15, electerm is vulnerable to arbitrary local code execution via deep links, CLI --opts, or crafted shortcuts. Exploit requires clicking a crafted electerm://... link or opening a crafted shortcut/command that launches electerm with attacker-controlled opts. This issue has been patched in version 3.8.15.

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.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. In versions 3.8.15 and prior, the getConstants() IPC handler in src/app/lib/ipc-sync.js serialises the entire process.env object and sends it to the renderer. The data is stored as window.pre.env and is accessible from any JavaScript running in the renderer (e.g., via the DevTools console or a compromised webview context). An attacker who achieves any JavaScript execution within the renderer can trivially exfiltrate these secrets to a remote server, leading to cloud account compromise, supply chain attacks, and lateral movement. At time of publication, there are no publicly available patches.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. In versions 3.8.15 and prior, Electerm's terminal hyperlink handler passes any URL clicked in the terminal directly to shell.openExternal without any protocol validation. An attacker who controls terminal output (e.g., via a malicious SSH server, compromised remote host, or malicious plugin rendering terminal content) can thus achieve arbitrary code execution or local file access on the victim's machine, requiring only that the victim clicks a displayed link. At time of publication, there are no publicly available patches.

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to version 3.7.16, the runWidget function in src/app/widgets/load-widget.js constructs a file path by directly concatenating user‑supplied widget identifiers without any sanitisation. Because runWidget is exposed to the renderer process via an asynchronous IPC handler with no input validation, an attacker who achieves JavaScript execution inside the renderer (for example, through a malicious plugin or a cross‑site scripting flaw in the built‑in webview) can abuse a path traversal (../) to load and execute an arbitrary JavaScript file anywhere on the victim’s filesystem. This gives the attacker local code execution with the full privileges of the electerm process, leading to complete system compromise. This issue has been patched in version 3.7.16.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
