ProhostAI — agentic threat model
ProhostAI acts as an automated assistant for vacation rental hosts, introducing risks related to guest PII exposure, unauthorized booking modifications, and potential manipulation of smart lock or check-in instructions if integrated with property management systems.

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.
Not certain from the listing — The underlying foundation models are not specified, but adversarial prompt injection could lead to the agent leaking host secrets, bypass booking policies, or generating inappropriate guest communications.
Not certain from the listing — The agent likely processes sensitive property details, check-in instructions, and guest PII. Without secure RAG and data isolation, there is a risk of data exfiltration or cross-tenant data leakage.
Not certain from the listing — The orchestration framework is unspecified. Insecure tool integration with Property Management Systems (PMS) or messaging APIs could allow attackers to manipulate bookings or send unauthorized messages.
Not certain from the listing — Hosting and infrastructure details are absent. Secure storage of API keys for vacation rental platforms (e.g., Airbnb, Guesty) is critical to prevent lateral movement and account takeover.
Not certain from the listing — No observability or guardrail mechanisms are mentioned. Real-time monitoring is necessary to detect hallucinated check-in codes, incorrect pricing, or abusive automated guest interactions.
Not certain from the listing — Compliance with privacy regulations (like GDPR/CCPA) is critical due to handling guest PII, but no specific security certifications or access control policies are detailed.
Not certain from the listing — The agent likely operates within a single-agent paradigm but interacts with external ecosystems (OTAs, PMS, smart lock APIs) where trust boundaries must be strictly enforced.
