Beauty

Security checks for vulnerabilities and agentic risk

Overview

This is a local, instruction-only beauty guidance skill with disclosed opt-in memory and no external data sharing.

Before installing, know that the skill may save beauty preferences and routine context locally under ~/beauty only if you approve it. Avoid saving medical diagnoses or sensitive identifiers, and review or delete ~/beauty/memory.md if you no longer want that context 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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill instructs storing durable personal context such as skin/scalp profile, sensitivities, budget, and typical routines in local memory, but it does not require a clear user-facing privacy notice or explicit consent for ongoing persistence of that data. While the storage is local and later file permissions are restrictive, this still creates privacy risk because users may not realize health-adjacent and lifestyle information is being retained across sessions.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The file gives generalized skincare routines, including exfoliation and recovery guidance, without a clear warning to patch test new products and discontinue use if irritation increases. In a beauty skill, users may follow these steps directly, so omission of basic safety guidance can contribute to worsening irritation or inappropriate continued product use.
