Ava — agentic threat model
Ava presents a moderate-to-high risk profile due to its integration with sensitive communication channels (Gmail, Google Calendar) and its processing of high-value real estate contracts containing PII and financial data. The primary threat vector is prompt injection via untrusted contract documents leading to unauthorized email dispatch or timeline manipulation.

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 unspecified. The primary threat is indirect prompt injection via malicious text embedded within uploaded real estate contracts, which could manipulate the model's timeline generation or email drafting behavior.
Ava ingests and processes highly sensitive real estate contracts containing PII, financial terms, and critical dates. Threats include data exfiltration of sensitive transaction details and unauthorized access to stored contract data.
The agent orchestrates workflows, extracts timeline dates, and calls external tools (Gmail, Google Calendar). Threats include insecure tool integration where manipulated outputs trigger unauthorized email dispatches to transaction parties or incorrect calendar scheduling.
Not certain from the listing — The hosting environment and document parsing sandbox controls are not detailed. Threats include server-side request forgery (SSRF) or remote code execution (RCE) during the parsing of untrusted PDF/Word contracts.
Not certain from the listing — No observability, logging, or guardrail mechanisms are mentioned. This creates a blind spot where incorrect timeline extractions or malicious email drafts may go undetected before execution.
Not certain from the listing — Compliance with financial or real estate data privacy regulations (e.g., GLBA) and identity/access management controls for Gmail/Calendar OAuth are not specified.
Ava operates as a vertical, single-agent transaction assistant without multi-agent collaboration or marketplace interactions, minimizing ecosystem-specific cascading risks.
