Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward campsite-availability checker that makes disclosed Recreation.gov API requests and does not show hidden persistence, credential access, or destructive behavior.

Before installing, understand that running the checker will contact Recreation.gov and may make extra per-site API calls when amenity filters are used. It does not require credentials or install dependencies, but users should avoid excessive bulk querying and verify availability on Recreation.gov before booking.

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 documentation instructs users to run a Python script that performs external queries to recreation.gov, but the skill manifest does not declare any tool scope such as network permissions or allowed-tools. This creates a transparency and policy-enforcement gap: agents or reviewers cannot accurately reason about what external access the skill requires, increasing the chance of unreviewed network interactions or misuse in environments that rely on manifest-based restrictions.
