Security audit

api-integration - API 集成

Security checks for vulnerabilities and agentic risk

Overview

This is a small instructional API-integration skill with expected examples for REST, OAuth, and GraphQL, and no hidden execution or persistence behavior.

This skill appears safe to install as instructional material. When using its API examples, review the destination endpoint and avoid sending passwords, tokens, client secrets, personal data, or workspace data unless the target service is trusted and the user has approved that transmission.

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

Missing User Warnings

Finding

This markdown skill describes connecting to third-party APIs and includes examples of sending requests and using client credentials, but it does not warn users that API calls may transmit user/system data or that authentication secrets must be handled carefully. For a skill centered on external integrations, omitting a user-facing warning about privacy and credential exposure is a meaningful safety gap.
