K G — agentic threat model

8.6AIVSS 8.6 · High

K G is a VS Code-integrated coding agent with deep workspace contextual awareness, presenting high risk of local file system compromise, arbitrary code execution, and supply chain poisoning if compromised or fed malicious context.

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 — the specific foundation models used are not disclosed. General threats include adversarial prompt injection causing the model to generate insecure or backdoored code, and model reprogramming.

L2 · Data Operations✓ mapped

The agent reads and indexes the entire project workspace to build context. Threats include codebase poisoning (where malicious files in the repository inject instructions into the context window) and unauthorized exfiltration of proprietary source code.

L3 · Agent Frameworks✓ mapped

The framework orchestrates file system reads/writes and VS Code API interactions. Threats include insecure tool integration, where the agent could be manipulated into overwriting critical configuration files or executing malicious scripts via terminal tools.

L4 · Deployment & Infrastructure✓ mapped

Deployed locally as a VS Code extension. The primary threat is host compromise, as the extension typically runs with the user's local privileges, lacking sandbox isolation from the developer's primary operating system.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — there is no mention of built-in guardrails, output sanitization, or logging mechanisms to detect and block the generation of malicious code or insecure dependencies.

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

Not certain from the listing — while the agent is open source (allowing code audit), there are no mentioned enterprise security policies, access controls, or compliance certifications.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — no multi-agent orchestration or external agent marketplace interactions are described, limiting the threat surface to the local VS Code extension ecosystem.
