Ralph — agentic threat model

9.3AIVSS 9.3 · Critical

Ralph is a highly autonomous coding agent with direct bash execution capabilities, presenting a significant security risk if exposed to untrusted PRDs or codebases due to the lack of sandboxing and human-in-the-loop controls.

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 — relies on external models via Claude Code or Amp CLI. Threats include prompt injection via malicious PRD files or codebase comments, which could hijack the agent's execution flow.

L2 · Data Operations✓ mapped

Uses git history, prd.json, and progress.txt for state and context. Threats include data poisoning where a malicious PRD or modified git history manipulates the agent's state machine, goals, or file writes.

L3 · Agent Frameworks✓ mapped

Orchestrates an autonomous loop running Amp CLI/Claude Code and executing bash automation. High risk of tool misuse (arbitrary bash execution) and insecure tool integration if input PRDs are untrusted.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — likely runs locally on developer machines or in CI/CD pipelines. Lacks sandboxing details, posing severe risks of host compromise, privilege escalation, and lateral movement via bash execution.

L5 · Evaluation & Observability✓ mapped

Uses progress.txt and git history to track state. However, there are no mentioned security guardrails, real-time monitoring, or anomaly detection to catch malicious code generation or destructive bash commands.

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

Not certain from the listing — no built-in authentication, authorization, or policy enforcement mechanisms are mentioned. Operates with the permissions of the local user/git SSH keys.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — primarily a single-agent loop, but interacts with external CLI tools (Claude Code, Amp CLI). Risks include cascading failures if these external tools or their APIs are compromised.
