Agent4Rec — agentic threat model
Agent4Rec (CACA Agent) presents a moderate risk profile as an open-source research and simulation framework; its primary hazards stem from the dynamic integration of tools via a Tool Broker without native sandboxing or access controls.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
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 — The description mentions reducing reliance on a single LLM through collaborative capabilities, but does not specify which foundation models are supported. Threats include prompt injection affecting the planning and methodology capabilities.
The agent utilizes the MovieLens dataset for user behavior simulation. Threats include data poisoning of the simulation datasets, which could bias the recommender system simulation results.
Features explicit Planning, Methodology, and Tools Capabilities with a Tool Broker. Threats include tool misuse, insecure tool integration, and hijacking of the Tool Broker to execute unauthorized services.
Not certain from the listing — As an open-source research framework, deployment details are unspecified. Lack of sandboxing for the Tool Service could allow local path traversal or arbitrary code execution on the host.
Not certain from the listing — No built-in guardrails or logging mechanisms are detailed. This creates blind spots in monitoring simulated user behaviors and tool execution paths.
Not certain from the listing — There is no mention of authentication, authorization, or access controls for the Tool Broker or Tool Service, posing compliance risks if deployed in production.
Designed for capability collaboration and multi-agent simulation. Threats include cascading failures across collaborative capabilities and trust abuse between the Tool Broker and external Tool Services.

These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification.
