Dropbox Download

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Dropbox file-download tool that sends a user-chosen path to Dropbox and returns the file content.

Install only if you intend to let the agent download files from your Dropbox. Use a Dropbox connection scoped to file-content read access, and only provide paths for files you want the tool to retrieve.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

Finding

This manifest file defines an HTTP tool that sends user-provided input to the Dropbox API, but the description only says it will download a file and does not warn that the path input is transmitted to an external service. For markdown and code scopes this would be expected disclosure, and for this manifest the omission is still visible in the skill description tied to the network action.
