Security audit
New Contact Hygiene Workflow
Security checks for vulnerabilities and agentic risk
Overview
This skill is a transparent manual guide for creating a HubSpot contact-cleanup workflow, with no hidden code or automatic local execution.
Before installing or using this skill, confirm you want a HubSpot workflow that runs on all new contacts and may overwrite contact company and industry fields from the primary associated company. If using the optional Chrome extension route, consider that it will interact with your authenticated HubSpot UI, so use it only in an account and browser profile you trust.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
