WebView2 Security Hardening: Preventing Host Sandbox Escapes

WebView2 Security Hardening: Preventing Host Sandbox Escapes featured header illustration

Modern desktop applications often display third-party web content inside their interfaces.

If this third-party content is compromised, it can attempt a sandbox escape, executing malicious scripts directly on the host operating system.

Strict IPC Context Isolation

NextGen DLM hardens WebView2 by disabling any direct script injection APIs and using strict IPC context isolation.

The frontend cannot execute shell commands directly. It can only request system activities via a strictly scoped, type-safe API parsed by the Rust backend.

OS Sandbox Containment

By forcing WebView2 process boundaries to run under low-integrity OS levels, system storage and kernel spaces are completely shielded from potential attacks.
