Pinterest API - Search, Pins, Boards, Profiles

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Pinterest data lookup integration that clearly discloses its Scavio API use and required API key.

Before installing, make sure you are comfortable sending Pinterest queries, usernames, pin or board URLs, and URL-stat lookups to Scavio, and monitor API credit usage because calls consume credits.

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
