+## RCE: Webview CSP + postMessage trust + local file loading (VS Code 1.63)
+
+This real-world chain affected Visual Studio Code 1.63 (CVE-2021-43908) and demonstrates how a single markdown-driven XSS in a webview can be escalated to full RCE when CSP, postMessage, and scheme handlers are misconfigured. Public PoC: https://github.com/Sudistark/vscode-rce-electrovolt
+
+Attack chain overview
+- First XSS via webview CSP: The generated CSP included `style-src 'self' 'unsafe-inline'`, allowing inline/style-based injection in a `vscode-webview://` context. The payload beaconed to `/stealID` to exfiltrate the target webview’s extensionId.
+- Constructing target webview URL: Using the leaked ID to build `vscode-webview://<extensionId>/.../<publicUrl>`.
+- Second XSS via postMessage trust: The outer webview trusted `window.postMessage` without strict origin/type checks and loaded attacker HTML with `allowScripts: true`.
+- Local file loading via scheme/path rewriting: The payload rewrote `file:///...` to `vscode-file://vscode-app/...` and swapped `exploit.md` for `RCE.html`, abusing weak path validation to load a privileged local resource.
+- RCE in Node-enabled context: The loaded HTML executed with Node APIs available, yielding OS command execution.
+
+Example RCE primitive in the final context
+```js
+// RCE.html (executed in a Node-enabled webview context)
+require('child_process').exec('calc.exe');            // Windows
+require('child_process').exec('/System/Applications/Calculator.app'); // macOS
+```
