Electerm Local code through electerm's single-instance socket

Impact

Local code execution without UI interaction: any same-user process can send a JSON payload to electerm's single-instance socket/pipe, causing the app to create tabs and potentially spawn attacker-controlled local processes. Affects electerm single-instance installs on the machine.
