BLINK_FEATURES_JS_CHECK

BLINK_FEATURES_JS_CHECK - Do not use Chromium’s experimental features

The blinkFeatures / enableBlinkFeatures flag can be used to selectively enable Blink (Chromium web browser engine) features, which increases the overall attack surface for production applications.

---

Risk

Experimental features may introduce bugs and increase the attack surface of the application.

Auditing

Search for blinkFeatures / enableBlinkFeatures flags set to true within the webPreferences of BrowserWindow:

mainWindow = new BrowserWindow({
  "webPreferences": {
    "enableBlinkFeatures": "CSSVariables"
  }
});
