1Person

Security checks for vulnerabilities and agentic risk

Overview

This skill is a brief, disclosed integration for the 1Person external assistant service and requires an API key, with no bundled executable code or hidden install behavior found.

Before installing, treat this as an external-service skill: protect ONEPERSON_API_KEY like a password, avoid sending sensitive work unless you trust 1Person's policies, and check how its persistent memory can be reviewed or deleted.

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 markdown instructs users to obtain and set `ONEPERSON_API_KEY`, which implies the skill will use sensitive credentials and communicate with an external service. The description does not include any warning about sharing data with the service, protecting the API key, or privacy/system impact.
