Perplexity — agentic threat model

7.5AIVSS 7.5 · High

Perplexity presents a moderate risk profile primarily driven by its real-time web-scraping and RAG capabilities, which are susceptible to data poisoning and prompt injection, though its lack of write-access to external systems limits its direct operational impact.

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 — Perplexity uses advanced closed-source and open-source LLMs. Threats include prompt injection, model reprogramming, and adversarial inputs designed to bypass safety filters.

L2 · Data Operations✓ mapped

Perplexity relies heavily on real-time web scraping and RAG. This exposes it to data/knowledge-base poisoning (SEO manipulation, adversarial web pages) and data exfiltration via prompt injection.

L3 · Agent Frameworks⚠ not certain from listing

Not certain from the listing — The orchestration layer manages query planning and tool execution (search APIs). Threats include insecure tool integration and prompt injection leading to unintended search queries.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — Hosting and sandboxing details are not provided. The web scraping infrastructure is highly vulnerable to SSRF, IP blocking, and potential container compromise if executing untrusted JS from scraped sites.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — No details on monitoring or guardrails are provided. Gaps here could lead to undetected drift, hallucinated answers, or undetected prompt injection attacks.

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

Not certain from the listing — Compliance certifications (e.g., SOC2, ISO) and identity/auth policies are not mentioned, leaving potential gaps in user data privacy and access controls.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — No multi-agent or marketplace interactions are described, though future integrations could introduce cascading trust issues.
