Security audit

Pipeworx iconify

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent icon-search integration, but its MCP setup automatically runs an unpinned third-party npm package, so users should review it before installing.

Install only if you are comfortable with a remote MCP service and an npm-based launcher. Prefer pinning mcp-remote to a reviewed exact version, avoiding automatic -y installs where possible, and running the MCP client with minimal file, credential, and environment access.

A.I.G

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

Install the dependency through a committed lockfile and use a reproducible installation method such as `npm ci`. 4. Verify the package using registry integrity metadata, cryptographic provenance, and publisher/repository ownership before deployment. 5. Prefer a locally installed, audited launcher rather than downloading executable code at MCP startup. 6. Use dependency monitoring and require explicit review before updating the pinned version. 7. Run the MCP launcher in a restricted environment with minimal filesystem access, limited credentials, constrained network access, and no administrative privileges. ]]>
