Buildel — agentic threat model
Buildel is an open-source visual workflow builder that orchestrates external AI models and APIs. Its primary security risks stem from the handling of user-provided API keys (BYOK) and the potential for insecure API integrations or SSRF via its modular workflow blocks.

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.
Integrates with multiple external AI providers using a 'Bring Your Own Keys' (BYOK) model. Risks are primarily inherited from these external foundation models, including prompt injection and misaligned outputs, rather than hosted model vulnerabilities.
Not certain from the listing — Supports 'document search' which implies RAG capabilities and vector database integration, but the specific data handling, storage, and embedding inversion protections are not detailed.
The core of Buildel is its visual workflow builder and modular blocks (text I/O, chat, API calls). Vulnerabilities here include insecure tool integration, workflow logic bypasses, and untrusted input handling within the orchestration framework.
Not certain from the listing — As an open-source platform, deployment is likely self-hosted or cloud-hosted by the user. Sandboxing of API execution blocks and secure storage of API keys at rest are critical but unspecified infrastructure concerns.
Not certain from the listing — The directory listing does not mention built-in evaluation, logging, or guardrail mechanisms to monitor workflow execution or detect anomalous API calls.
Not certain from the listing — Beyond the 'Bring Your Own Keys' model for external APIs, there is no mention of built-in identity management, role-based access control (RBAC), or compliance certifications.
Not certain from the listing — While it allows building complex integrations and workflows, there is no explicit mention of a multi-agent ecosystem, agent-to-agent trust boundaries, or a shared marketplace.
