How to Stream Live Browser Feeds from AI Agents to React Dashboards in Real Time

·5 views

As AI agents grow capable of autonomously navigating web applications and executing transactions, monitoring them through text logs alone is no longer sufficient. Developers now need real-time visual feeds of what an AI agent is doing inside a headless browser, down to sub-100-millisecond latency. A streaming pipeline can be built by connecting a browser automation runner using tools like Playwright or Puppeteer to a React frontend via a WebSocket gateway. The architecture captures raw visual frames using Chrome DevTools Protocol's Page.startScreencast method, which is more efficient than screenshot polling loops. This approach is especially critical for use cases like AI governance dashboards, where human supervisors must instantly detect and halt unauthorized agent actions.

Chrome 151 drops Manifest V2 support, forcing workarounds to keep uBlock Origin

Google Chrome version 151 has fully removed support for Manifest V2 extensions, effectively blocking full-featured ad blockers like uBlock Origin from running. A developer workaround for macOS involves downgrading to Chrome 150.0.7871.187 and preventing the browser from auto-updating to preserve MV2 compatibility. Users must also launch Chrome with specific flags via an Automator app and manually load the uBlock Origin extension in developer mode. However, staying on an outdated browser carries real risks, including exposure to unpatched security vulnerabilities and loss of access to newer web platform features. For those unwilling to accept these trade-offs, switching to Firefox or Safari remains the recommended alternative.

Switching from jsdom to happy-dom fixes Vitest worker crashes in GitHub Actions CI

A development team found that their Vitest test suite ran successfully locally but crashed entirely on GitHub Actions before executing a single test. The root cause was traced to a compatibility issue inside jsdom's bundled undici dependency, which failed during worker pool initialization with the error 'webidl.util.markAsUncloneable is not a function'. Because none of the test files ever started running, the CI pipeline reported 0% code coverage and a broken build. The team resolved the issue by replacing jsdom with happy-dom, a lighter test environment that implements only the browser APIs commonly needed for modern frontend unit testing. The fix was applied to a Next.js monorepo using pnpm, Vitest, and GitHub Actions running Node.js 20 on Ubuntu.

TryHackMe 'Infinity Pool' CTF: Dual Command Injections Lead to Root Access

A TryHackMe capture-the-flag challenge called 'Infinity Pool' centered on a fictional hotel website called 'Byte Lotus', hosted via Gunicorn on port 80. An unsanitized host parameter in an internal network-check tool allowed OS command injection, granting an initial foothold and the user flag. An internally exposed operations console on port 3000 leaked unrotated FreePBX credentials, and accessing its dashboard via SSH port forwarding revealed a bearer token hidden in a caller-ID field. That token authenticated to a root-run automation service on port 9000, whose report parameter was also unsanitized, enabling a second command injection as root. Chaining these two vulnerabilities — both classic command injection flaws stemming from missing input sanitization — ultimately yielded the root flag.
