Devyan — agentic threat model

9.6AIVSS 9.6 · Critical

Devyan presents a high agentic risk profile due to its multi-agent orchestration of software development tasks, which likely involves executing generated code (e.g., during testing) and accessing sensitive code repositories without built-in sandboxing or verification controls.

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✓ mapped

Uses OpenAI's GPT-based models. Vulnerable to prompt injection that could hijack the developer, architect, or tester roles to inject malicious code or bypass design constraints.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — likely reads local codebases or repositories, posing risks of data exfiltration or processing malicious source code (data poisoning) if the repository contains untrusted inputs.

L3 · Agent Frameworks✓ mapped

Orchestrates multiple agents for architecture, implementation, testing, and reviewing. Vulnerable to insecure tool integration (e.g., executing test suites that run arbitrary code) and orchestration logic bypasses.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — as an open-source coding agent, it likely runs locally or in user-provisioned environments. If not strictly sandboxed, code execution during the 'testing' phase poses severe host compromise risks.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — no explicit mention of logging, guardrails, or evaluation frameworks to monitor agent-to-agent communication or code generation safety.

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

Not certain from the listing — being open-source, compliance and access controls (authN/authZ) depend entirely on the user's deployment environment and API key management.

L7 · Agent Ecosystem✓ mapped

Employs a multi-agent ecosystem (architecture, implementation, testing, reviewing). Vulnerable to agent-to-agent trust abuse, where a compromised implementation agent fools the reviewer agent, leading to cascading security failures in the generated software.
