CVE-2026-43942 · electerm: Full process.env exposed to renderer via window.pre.env in electerm
Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.
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.
