🤖 THE AI FRONTIER

• Attackers Compromise Langflow AI Pipelines in 20 Hours

  • The Risk: A critical vulnerability (CVE-2026-33017) in the Langflow visual framework for AI agents was exploited in the wild within 20 hours of disclosure. Attackers used automated scanning and custom scripts to harvest API keys and high-value data, highlighting the rapid weaponization of AI infrastructure flaws.
