Fitness Support

Security checks for vulnerabilities and agentic risk

Overview

This is a fitness coaching skill with disclosed progress-memory behavior, but users should be mindful that it may store personal fitness and health-related notes.

Before installing, consider whether you are comfortable having workout history, injury limitations, sleep, and nutrition notes stored in the skill's memory file. Avoid adding sensitive medical details unless needed, and delete or edit the memory file if you no longer want that information retained.

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

Finding
The skill explicitly states it maintains a memory file containing workout history, injuries or limitations, and nutrition or recovery patterns, which are health-related personal data. Because the skill does not disclose retention, access, or privacy implications to the user before encouraging collection of this data, it creates a real privacy risk through uninformed consent and unnecessary storage of sensitive information.
