changelog-generator — agentic threat model

5.1AIVSS 5.1 · Medium

The changelog-generator poses low agentic risk due to its read-only nature and lack of autonomous write capabilities, though it remains susceptible to prompt injection via malicious commit messages and potential exposure of sensitive git history data.

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 — likely uses a standard LLM for text rewriting. Primary threats include prompt injection via malicious git commit messages designed to hijack the model's output or exfiltrate data.

L2 · Data Operations✓ mapped

The primary data source is the git repository's commit history. Threats include reading sensitive information (secrets, keys) accidentally committed to the history, or processing poisoned commit messages.

L3 · Agent Frameworks⚠ not certain from listing

Not certain from the listing — likely implemented as a simple script or basic LLM orchestrator. Vulnerabilities could arise from insecure execution of git commands (e.g., command injection if repo names or parameters are untrusted).

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — likely runs locally as a CLI tool, a CI/CD runner (e.g., GitHub Actions), or a hosted plugin. If run in CI/CD, a compromise could expose repository secrets or CI environment variables.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — likely lacks active guardrails or output evaluation, relying entirely on the user to review the generated changelog before publishing.

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

Not certain from the listing — as an open-source plugin, it likely lacks formal compliance certifications (SOC2/ISO) and relies on the host environment's access controls to restrict repository access.

L7 · Agent Ecosystem✓ mapped

This agent operates standalone to generate changelogs and does not interact with an agent ecosystem or other marketplace agents, minimizing multi-agent cascading risks.
