dependency-management — agentic threat model

8.4AIVSS 8.4 · High

This agent presents a moderate-to-high risk profile due to its direct access to local project files, dependency manifests, and execution of system-level audit tools, which could be exploited to execute malicious code or compromise the software supply chain.

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 — relies on the underlying Claude Code model. Threats include prompt injection leading to the bypass of dependency checks or the recommendation of malicious packages.

L2 · Data Operations✓ mapped

Reads local project lockfiles, manifests, and dependency trees. Risk of data exfiltration of proprietary code structure or poisoning of the dependency manifests analyzed by the agent.

L3 · Agent Frameworks✓ mapped

Integrates subagents for auditing and version management. Vulnerable to tool misuse where the agent is tricked into running arbitrary system commands or installing compromised packages during the upgrade process.

L4 · Deployment & Infrastructure✓ mapped

Runs locally as a Claude Code plugin. If executed without sandboxing, a compromised agent can escalate privileges, access local environment variables, or modify local files outside the project scope.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — lacks explicit mention of logging, guardrails, or verification steps to ensure recommended dependency upgrades are safe before execution.

L6 · Security & Compliance (cross-cutting)✓ mapped

Open-source and free, but lacks built-in compliance frameworks or automated policy enforcement to prevent the introduction of licenses or packages that violate corporate policies.

L7 · Agent Ecosystem✓ mapped

Bundles multiple subagents (auditing, versioning, scanning). Vulnerable to cascading failures or trust abuse if one subagent is compromised and influences the actions of the others.
