Zapier workflows/install — agentic threat model

9.3AIVSS 9.3 · Critical

This agent possesses high-risk capabilities due to its ability to perform account-level write actions, wire connections, and publish workflows within Zapier. A compromise could allow unauthorized deployment of malicious integrations, leading to widespread data exfiltration across connected third-party services.

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 — The underlying foundation model is not specified, but vulnerabilities like prompt injection could lead to unauthorized workflow modifications or connection hijacking.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — No details on RAG or vector stores are provided, but the agent must ingest workflow definitions, risking injection of malicious workflow schemas.

L3 · Agent Frameworks✓ mapped

The agent framework orchestrates Zapier API calls to install and publish Zaps. Insecure tool integration or prompt injection could allow an attacker to manipulate connection wiring or publish unauthorized, data-exfiltrating workflows.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — The hosting environment (likely Zapier's infrastructure or a self-hosted environment given 'Open Source') is unspecified, posing risks of credential exposure if API keys are poorly secured.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — No logging, guardrails, or evaluation metrics are mentioned, creating a blind spot for unauthorized workflow activations or connection modifications.

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

The agent performs high-privilege, account-level write actions (wiring connections, publishing Zaps). Without strict OAuth scopes, least-privilege enforcement, or human-in-the-loop approval, it poses significant compliance and authorization risks.

L7 · Agent Ecosystem✓ mapped

As an 'Agent Skill', this tool is designed to be integrated into larger multi-agent systems or marketplaces. Compromise of a calling agent could lead to cascading authorization abuse, allowing malicious agents to silently deploy backdoored workflows.
