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._

AnalysisAI
Local code execution in electerm 3.0.6 through 3.8.8 allows any same-user process to send a crafted JSON payload to electerm's single-instance IPC socket/pipe, causing the application to open tabs with attacker-controlled exec paths, arguments, environment variables, and post-connect scripts that spawn arbitrary local processes. No public exploit identified at time of analysis, but the GHSA advisory and patch commit confirm the vulnerability is real, scored CVSS 4.0 9.3 (Critical), and fixed in version 3.9.0 by filtering dangerous tab properties on the IPC boundary.
