Fitbit
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward Fitbit helper that tells the agent how to run a local Fitbit CLI for read-only health and device queries.
Before installing, make sure you trust the fitbit-cli tool and are comfortable letting the agent read Fitbit health, profile, and device data when you ask related questions. Review where fitbit-cli stores OAuth tokens on your machine and revoke Fitbit access if you no longer use it.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
