AiderDesk — agentic threat model

9.6AIVSS 9.6 · Critical

AiderDesk presents a high-risk agentic profile due to its desktop orchestration capabilities, where third-party TypeScript extensions can execute arbitrary code, register custom tools, and hook into 30+ lifecycle events with minimal 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.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — AiderDesk is model-agnostic and relies on external LLMs via Aider; threats include prompt injection leading to unauthorized execution of registered slash-commands or tools.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — The tool operates on local workspace files (e.g., onFileAdded hook); threats include local data exfiltration or unauthorized file modification via malicious prompt injection.

L3 · Agent Frameworks✓ mapped

High risk. The framework exposes 30+ lifecycle hooks (onTaskCreated, onToolCalled) and allows TypeScript extensions to register custom tools and slash-commands, creating a massive attack surface for tool misuse and arbitrary code execution.

L4 · Deployment & Infrastructure✓ mapped

High risk. As a desktop orchestration app, extensions and tools run locally on the user's machine. Without explicit sandboxing mentioned, compromised extensions can achieve full local host compromise and privilege escalation.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — While lifecycle hooks (onToolCalled) exist and could theoretically be used for logging, there is no mention of built-in security guardrails, evaluation, or anomaly detection.

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

Not certain from the listing — No built-in authentication, authorization, or policy enforcement mechanisms are described for restricting what extensions or tools can execute on the host system.

L7 · Agent Ecosystem✓ mapped

High risk. The extension ecosystem allows custom agent profiles and third-party TypeScript plugins. A malicious or compromised plugin in the ecosystem can intercept core events and execute arbitrary background scripts.
