Agent Browser — agentic threat model

Not certain from the listing — The underlying foundation models are not specified. However, because the agent processes arbitrary web pages, it is highly vulnerable to indirect prompt injection, where malicious instructions embedded in web content hijack the model's behavior.

Not certain from the listing — The data storage, vector databases, and RAG mechanisms are not detailed. The primary data risk involves the temporary handling and potential exfiltration of sensitive user data entered into or scraped from web forms.

The agent framework translates plain-language goals into multi-step browser actions (form navigation, data collection). Threats include tool misuse, where the planning engine is tricked into executing unintended actions like submitting forms with malicious payloads or clicking malicious links.

Not certain from the listing — The deployment architecture (e.g., whether the browser runs in a secure, isolated cloud sandbox or locally) is not specified. A lack of strict sandboxing could allow a compromised browser session to perform SSRF or access local network resources.

The agent includes strong observability features, specifically screenshot-based evidence trails and reviewable audit trails. This mitigates the threat of silent failures, though there remains a risk of log tampering if the agent's execution environment is fully compromised.

The agent defines 'operator safety boundaries' to restrict actions, but the listing lacks details on enterprise-grade security controls such as role-based access control (RBAC), credential management for web forms, or compliance certifications.

Not certain from the listing — There is no mention of multi-agent orchestration or integration with an agent marketplace, suggesting ecosystem-level threats are currently out of scope.
