Operators running exposed Ruflo instances are being told to close ports 3001 and 27017, rotate all LLM API keys, and inspect for tampering after disclosure of CVE-2026-59726. The guidance applies to network-reachable deployments of Ruflo that could be abused for command execution, key theft, and persistent AI-memory poisoning. The recommended response is immediate because exposed instances were described as fully exploitable without authentication.
