Unpatched Langflow Flaw CVE-2026-5027 Exploited for Unauthenticated RCE

### Executive summary: A high-severity, unpatched path traversal vulnerability (CVE-2026-5027, CVSS 8.8) in the Langflow low-code AI orchestration platform is being actively exploited in the wild to achieve unauthenticated remote code execution; organizations should assume internet-exposed instances are at imminent risk, immediately isolate or take them offline, rotate exposed credentials, monitor for traversal patterns (e.g., '../' or encoded equivalents), and apply a vendor patch as an emergency update when released.
