Capterra Reviews API - Software Search, Pricing, Reviews

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent guide for using Scavio's Capterra API, with disclosed API-key use and no evidence of hidden persistence, local data access, or deceptive behavior.

Install only if you are comfortable using Scavio as an external paid API provider. Keep SCAVIO_API_KEY out of source control, monitor credit usage, and use an isolated environment or direct HTTPS calls if you want to avoid SDK supply-chain exposure.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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
