Electerm IPC Handler Command Injection Vulnerability

Publication date: 2026-09-08

Last updated on: 2026-09-08

Assigner: VulnCheck

Description

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.

Attack-Flow Graph

Executive Summary

This vulnerability affects electerm before version 5.3.15. It allows renderer-side scripts to execute system commands in the main process by invoking functions like openFileWithEditor through an unvalidated Electron IPC handler. The handler lacks a function-name allowlist or sender validation, enabling arbitrary function calls with malicious arguments.

Impact Analysis

An attacker could exploit this to run arbitrary system commands on your machine if you use a vulnerable version of electerm. This could lead to unauthorized file access, data theft, or installation of malware. The attack requires the attacker to have access to renderer-side script execution.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations using vulnerable versions may face compliance violations, fines, or legal consequences if exploited.

Mitigation Strategies

Update electerm to version 5.3.15 or later to address the unvalidated IPC handler and function execution risks.
