SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

IPC-based security in Tauri apps can be error-prone and hard to audit; this guide clarifies how runtime authority enforces permissions, capabilities, and scope injections to prevent unauthorized actions.

Core Features & Use Cases

ACL-based permission checks between the WebView frontend and Rust commands to block unauthorized IPC.
Runtime capability resolution that merges window-specific permissions and platform targeting.
Scope injection that constrains command behavior and prevents risky operations.

Quick Start

Define a capability for a window that allows a specific command only within a restricted scope and ensure the origin is validated before execution.

FAQPage Schema

How do I enforce secure IPC between a Tauri WebView frontend and Rust commands?▼

To enforce secure IPC in Tauri, you use the runtime authority to validate origins, permissions, and capabilities before allowing a command to execute. This blocks unauthorized WebView frontend actions against Rust commands.

How does Tauri runtime authority handle permission checks and capability resolution?▼

Tauri runtime authority performs ACL-based permission checks and merges window-specific permissions with platform targeting. This capability resolution ensures only authorized commands execute within their permitted contexts.

What are scopes in Tauri and how do they prevent risky IPC operations?▼

Scopes in Tauri constrain command behavior by injecting restrictions during runtime authority validation. This scope injection prevents risky operations by limiting what an authorized command can actually access or execute.

Can I apply platform-specific restrictions to Tauri capabilities and permissions?▼

Yes, Tauri runtime authority supports platform targeting during capability resolution. You can apply platform-specific restrictions to ensure capabilities and permissions are enforced differently depending on the operating system.

Why are my Tauri IPC commands blocked despite having the correct permissions configured?▼

Tauri runtime authority enforces deny-before-allow rules, meaning explicit deny rules override allow permissions. Your commands may be blocked because a deny rule is triggering before the allow permission is evaluated.

What is the best way to audit and prevent unauthorized IPC actions in Tauri apps?▼

The best way to prevent unauthorized IPC actions is using Tauri runtime authority to enforce ACL-based permission checks, validate origins, and inject scopes. This clarifies capabilities and blocks unauthorized commands.
