Sixeye Voice Ai Agent — agentic threat model

9.1AIVSS 9.1 · Critical

The Sixeye Voice AI Agent presents a moderate-to-high risk profile due to its direct integration with telephony (SIP) and enterprise systems (CRMs, calendars), which could be exploited via voice-based prompt injection to perform unauthorized data modifications or toll fraud.

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 models for voice synthesis and LLM processing are not specified. However, they are inherently vulnerable to voice-based prompt injection (jailbreaking via audio) and adversarial inputs designed to bypass safety guardrails.

L2 · Data Operations✓ mapped

The agent utilizes a customer-provided knowledge base for RAG. This introduces risks of knowledge-base poisoning, where malicious or inaccurate data injected into the knowledge base could lead the agent to output harmful or incorrect instructions to callers.

L3 · Agent Frameworks✓ mapped

The agent supports custom functions and integrations to book meetings and update CRMs. Insecure tool integration or lack of strict input validation on these functions could allow an attacker to manipulate CRM records or exhaust calendar resources via conversational manipulation.

L4 · Deployment & Infrastructure✓ mapped

Features SIP Integration for low-latency voice calls. This exposes the deployment layer to telephony-specific threats, including SIP registration hijacking, toll fraud, and denial-of-service attacks targeting the voice gateway.

L5 · Evaluation & Observability✓ mapped

The listing highlights 'useful analytics to improve service' but does not detail real-time security monitoring, guardrails, or anomaly detection for malicious voice interactions, leaving potential blind spots in threat detection.

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

Not certain from the listing — There is no mention of compliance standards (e.g., SOC 2, HIPAA, GDPR), identity and access management (IAM) controls for CRM updates, or authentication mechanisms for SIP trunking.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — The agent appears to operate as a standalone horizontal solution without explicit multi-agent orchestration or marketplace dependencies, minimizing ecosystem-specific cascading risks.
