Security checks for vulnerabilities and agentic risk

Overview

The skill is rated benign with high confidence: scans found one privacy-related concern about publishing owner information, while the other assessed dimensions were rated okay.

Before installing, consider whether you are comfortable with a result that may publish owner information. The scanners note that the skill does not define appropriate owner details or require approval before disclosure; use only information you intend to make public.

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 required footer includes an "Owner" field, and the skill directs the agent to publish the result without defining what owner information is appropriate or requiring approval before disclosure. In this public promotional context, an agent could expose a user's identity or link them to a bot without consent, although the skill does not explicitly demand sensitive identifiers or demonstrate malicious intent.
