CVE-2026-33017 is a CVSS 9.8 unauthenticated RCE in the Langflow AI pipeline platform, chaining missing authentication (CWE-306) with code injection (CWE-94), and was actively exploited with confirmed data exfiltration within 20 hours of public disclosure. Any internet-exposed Langflow instance should be treated as potentially compromised; organizations should remove public exposure immediately, apply the vendor patch once a confirmed fix is verified against NVD, and preserve forensic artifacts on any exposed instance before patching. AI/ML and platform engineering teams should be notified and Langflow should be added as a tracked vulnerability class in the asset inventory.
