Pharmacies

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple nearby-pharmacy lookup guide that uses location data in a disclosed, purpose-aligned way.

Before installing, be aware that the skill needs your location to work. That access is expected for nearby pharmacy search, and the artifact says location should only be used with authorization and precise coordinates should not be retained unnecessarily.

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

Finding
The skill content is primarily written in Chinese, but key user-facing trigger phrases and category labels also include English terms like "Pharmacies" and "pharmacies near me". This imposes a mixed-language experience without documenting a user language preference or offering a locale choice, which can violate language/locale policy expectations.
