Box AI Agents — agentic threat model

6.9AIVSS 6.9 · Medium

Box AI Agents present a high-impact risk profile due to their deep integration with sensitive enterprise document repositories (HR, Legal, Finance) and workflow automation capabilities. While mitigated by Box's robust permissions-aware security architecture, vulnerabilities like prompt injection could lead to unauthorized data access or automated approval manipulation.

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

Integrates with external top LLM providers via Box AI Studio. Risks include adversarial prompt injection bypassing document boundaries, and potential data leakage to third-party LLM APIs if data-sharing agreements or zero-data-retention policies are misconfigured.

L2 · Data Operations✓ mapped

Processes highly sensitive unstructured enterprise documents (HR, Legal, Finance) using permissions-aware search and metadata extraction. Risks include indirect prompt injection via malicious document uploads designed to exfiltrate data or poison the search index.

L3 · Agent Frameworks✓ mapped

Orchestrates workflow automation and document approvals. Risks include insecure tool execution where an attacker manipulates the agent's decision-making flow to trigger unauthorized approvals or execute unintended workflow steps.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — Hosted within Box's enterprise cloud infrastructure. General risks include container breakout, API vulnerabilities in Box AI Studio, and insecure transit of document payloads to external LLM providers.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — Likely relies on Box's standard enterprise logging and audit trails. General risks include lack of specialized LLM alignment monitoring, drift in extraction accuracy, and silent failures in compliance checks.

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

Strong focus on permissions-aware access control, compliance, and governance. Risks include complex RBAC misconfigurations allowing horizontal privilege escalation across document repositories, or failures in mapping user identities to LLM context windows.

L7 · Agent Ecosystem✓ mapped

Allows creation of multiple tailored agents (HR, Finance, Legal) via Box AI Studio. Risks include cross-agent trust exploitation where a compromised HR agent accesses sensitive financial agent workflows or shares unauthorized context.
