Evo.ninja — agentic threat model

9.6AIVSS 9.6 · Critical

Evo.ninja presents a high agentic risk profile due to its autonomous execution loop, dynamic persona switching, and ability to execute functions across sensitive domains like software development and data analysis without built-in guardrails.

OWASP AIVSS score rationale

AIVSS = (CVSS_Base + AARS) × Mitigation_Factor, where AARS = (10 − CVSS_Base) × (Factor_Sum / 10) × ThM

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.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — The specific foundation models used by Evo.ninja are not detailed, leaving risks like model reprogramming, adversarial prompt injection, and data poisoning dependent on the user's choice of backend LLM.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — The mechanism for data ingestion, vector storage, and RAG is unspecified, making it unclear how the agent prevents data exfiltration or knowledge-base poisoning during research and data analysis tasks.

L3 · Agent Frameworks✓ mapped

Evo.ninja's core framework relies on a continuous execution loop that predicts the next step and executes functions. This creates a high risk of tool misuse, insecure function calling, and arbitrary code execution, especially when performing software development tasks.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — As an open-source tool, deployment is user-managed. Without explicit sandboxing or containerization guidelines in the listing, running Evo.ninja locally poses severe host compromise and privilege escalation risks.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — There is no mention of built-in evaluation, logging, or guardrail mechanisms to monitor the continuous execution loop or detect anomalous persona transitions.

L6 · Security & Compliance (cross-cutting)⚠ not certain from listing

Not certain from the listing — The listing does not outline any identity, authorization, or policy enforcement controls to restrict what actions the agent can perform on behalf of the user.

L7 · Agent Ecosystem✓ mapped

Evo.ninja dynamically selects and coordinates specialized personas in real-time. This multi-persona architecture introduces risks of cascading failures, persona-to-persona trust abuse, and unpredictable emergent behaviors during complex task execution.
