Hexabot — agentic threat model
Hexabot is an open-source chatbot and agent platform characterized by low-to-moderate agentic risk due to its reliance on structured visual flows rather than fully autonomous planning. The primary security vectors lie in its extensible plugin system and the self-hosted deployment model, which shifts infrastructure and model-level security responsibilities to the implementer.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — Hexabot is an orchestration platform, meaning the underlying foundation models (LLMs) and their associated risks (adversarial prompt injection, model poisoning) depend entirely on the developer's choice of integrated model APIs.
Not certain from the listing — While Hexabot manages conversational data and NLU, the specific vector databases, RAG pipelines, and data exfiltration protections are not detailed in the public directory listing.
Hexabot's core value lies in its visual flow editor, NLU management, and extensible plugin system. Framework-level threats include insecure plugin execution, logic bypasses within the visual flow editor, and vulnerabilities in how user inputs are parsed and routed to tools.
Not certain from the listing — As an open-source platform, deployment infrastructure (hosting, container sandboxing, secrets management for API keys) is managed by the user, leaving potential gaps in network isolation and privilege escalation if self-hosted insecurely.
Not certain from the listing — The description does not mention built-in evaluation, real-time monitoring, LLM guardrails, or anomaly detection capabilities to mitigate drift or malicious inputs.
Not certain from the listing — There is no mention of enterprise-grade security compliance (e.g., SOC2, ISO 27001), role-based access control (RBAC), or audit logging within the provided description.
Hexabot supports an extensible plugin system and multi-channel deployment. This introduces ecosystem risks, such as compromised third-party plugins executing malicious code or unauthorized actions propagating across connected communication channels.
