Security audit

Quarterly Database Cleanup

Security checks for vulnerabilities and agentic risk

Overview

This is a read-only HubSpot CRM audit skill that clearly fits its stated purpose, with only a minor local report-writing disclosure issue.

Before installing, confirm you are comfortable giving the agent read access to HubSpot CRM data through the configured API token and writing an audit report under reports/. Consider renaming the report if one already exists for the same quarter.

  • 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
