SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Electron IPC boundary is a critical security frontier; this Skill codifies the standards required to keep the main process safe from renderer-originated compromises and untrusted data flowing across processes.

Core Features & Use Cases

  • Enforces context isolation across BrowserWindows to prevent untrusted Renderer code from accessing Node.js in the main process.
  • Provides a strict preload-contract pattern where only whitelisted APIs are exposed to the Renderer via contextBridge.exposeInMainWorld.
  • Guides safe IPC channel design, payload validation, and path-safety checks for cross-process data flows.

Quick Start

Configure the Electron preload to securely expose IPC APIs and validate all renderer inputs.

FAQPage Schema
How do I secure Electron IPC boundaries between main and renderer processes?

Secure Electron IPC boundaries by enforcing context isolation, applying strict preload contracts, and validating cross-process payloads to prevent renderer compromises from affecting the main process.

What is context isolation in Electron and when do I need it for IPC?

Context isolation in Electron separates untrusted renderer code from Node.js APIs in the main process, and you need it whenever configuring cross-process data flows to ensure safe IPC channel design.

How do I expose IPC APIs safely using contextBridge in a preload script?

Expose IPC APIs safely by using a strict preload-contract pattern where contextBridge.exposeInMainWorld only whitelists specific APIs, ensuring the renderer cannot access unrestricted Node.js methods.

Does this approach prevent path traversal in cross-process IPC data flows?

Yes, this approach prevents path traversal by guiding safe IPC channel design and enforcing payload validation alongside path-safety checks for all cross-process data flows in production Electron apps.

What is the best way to validate renderer payloads in Electron main process?

The best way to validate renderer payloads is applying strict preload contracts and path-safety checks during channel creation, ensuring untrusted data flows are sanitized before reaching the main process.

Why does disabling context isolation compromise my Electron main process?

Disabling context isolation compromises the main process by allowing untrusted renderer code to directly access Node.js APIs, bypassing the secure IPC boundaries required to prevent cross-process attacks.
