Secure IPC Patterns
Implement best practices for IPC, including validation of sender frames, sanitization of inputs, and avoiding common security pitfalls.
Why Secure IPC Matters
Electron applications combine the power of web technologies with native desktop capabilities. This means different parts of your app (like the web page and the main process) need to communicate.
This communication is called Inter-Process Communication (IPC). If not handled carefully, IPC can become a major security weakness, allowing attackers to compromise your application or the user's system.
Understanding IPC Security Risks
Insecure IPC patterns can lead to severe vulnerabilities:
- Remote Code Execution (RCE): An attacker could execute arbitrary code on the user's machine.
- Cross-Site Scripting (XSS): Malicious scripts injected into the renderer could steal data or compromise the app's functionality.
- Privilege Escalation: A less-privileged renderer process could gain access to more powerful main process capabilities.
