Meteor — agentic threat model
Meteor operates as an intelligent browser agent, presenting high inherent risks due to its direct interaction with untrusted web content and potential access to active user sessions, compounded by a complete lack of documented security controls or sandboxing.

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 powering the browser's intelligence are unspecified. Threats include indirect prompt injection via malicious web page DOMs and adversarial manipulation of input fields.
Not certain from the listing — No details are provided on how browsing history, cookies, or session data are stored or isolated. Threats include data exfiltration of sensitive user session tokens and history poisoning.
Not certain from the listing — The orchestration framework for executing browser actions (clicking, typing, navigating) is undefined. Threats include tool misuse, such as executing unauthorized form submissions or clicking malicious links.
Not certain from the listing — It is unclear if the browser runs in a secure cloud sandbox, locally, or as a standard extension. Threats include local privilege escalation or container escape if hosted in an un-sandboxed environment.
Not certain from the listing — No monitoring, logging, or guardrails are described. Threats include blind spots regarding automated actions taken by the agent on sensitive websites and lack of audit trails.
Not certain from the listing — No compliance certifications (e.g., SOC2) or identity/authorization controls are mentioned. Threats include unauthorized session hijacking and lack of policy enforcement over sensitive domains.
Not certain from the listing — No multi-agent coordination or marketplace integrations are described. Threats include interacting with malicious external web APIs or compromised third-party browser extensions.
