Figviz — agentic threat model

5.5AIVSS 5.5 · Medium

Figviz is a low-risk, single-purpose diagram generation tool with minimal agentic capabilities, posing primary risks around content generation quality, web application security, and potential image-processing vulnerabilities rather than autonomous agent failures.

OWASP AIVSS score rationale

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

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.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — likely uses a text-to-image model (like Stable Diffusion) or a multimodal LLM to generate SVG/PNG diagrams. Threats include prompt injection leading to inappropriate content generation or model evasion.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — likely relies on pre-trained models without extensive RAG or vector databases, though custom STEM datasets might have been used. Threats include training data poisoning if fine-tuned on custom educational datasets.

L3 · Agent Frameworks⚠ not certain from listing

Not certain from the listing — the tool appears to be a simple single-turn generator rather than a complex agentic framework. Threats of tool misuse or memory poisoning are minimal due to the lack of agentic orchestration.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — hosted web application exporting PNGs. Threats include server-side image processing vulnerabilities (e.g., remote code execution via image libraries) and standard web application hosting risks.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — no mention of guardrails or output filtering. Threats include generation of offensive, biased, or highly inaccurate scientific diagrams (hallucinations) without automated detection.

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

Not certain from the listing — mentions a paid model with free credits, implying user accounts and billing. Threats include unauthorized access to user accounts, credit theft, and lack of compliance with educational privacy standards (e.g., COPPA/FERPA).

L7 · Agent Ecosystem✓ mapped

No multi-agent or marketplace interactions are described; the tool operates as a standalone single-user utility, making ecosystem threats currently inapplicable.
