🛡️ Sentinel: [CRITICAL] Fix XSS vulnerability in WebView#154TargetMisser wants to merge 1 commit intomainfrom
Conversation
🚨 Severity: CRITICAL 💡 Vulnerability: The `HomeScreen.tsx` and `ShiftScreen.tsx` files were vulnerable to Cross-Site Scripting (XSS) via `injectJavaScript` using string interpolation to pass dynamic data (base64 JSON strings) into the WebView. 🎯 Impact: This vulnerability could allow an attacker to execute arbitrary scripts in the context of the React Native application. 🔧 Fix: Removed `injectJavaScript` string interpolation and implemented a secure two-way communication channel using `postMessage`. Added event listeners in the WebView to handle messages and broadcast a 'READY' state to avoid race conditions. ✅ Verification: Ensure the app builds without errors via `npm run typecheck` and that OCR functionality is verified locally using `isEngineReady` tracking state.
