Affected Systems
Langflow open-source low-code AI platform, all unpatched versions. Vulnerability allows unauthenticated path traversal leading to arbitrary file write and remote code execution.
Exploitation Status
Active exploitation confirmed in the wild. No patch currently available.
Business Impact
Unauthenticated attackers can achieve remote code execution on exposed Langflow instances via path traversal, enabling full system compromise. Organizations running Langflow for AI workflow development face immediate risk of data breach, lateral movement, and infrastructure takeover. CVSS score 8.8 (high severity, though marked critical by source).
Urgency
🔴 Immediate
Recommended Actions
- Immediately isolate or disable internet-facing Langflow instances until patch is available
- Restrict Langflow access to trusted internal networks only via firewall rules or VPN
- Monitor web server and application logs for suspicious file write attempts or path traversal patterns (e.g., '../' sequences in requests)
- Audit Langflow deployments for indicators of compromise: unexpected files in web directories, new user accounts, or unauthorized processes
- Subscribe to Langflow security advisories and apply patch immediately upon release
