Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped email lookup and verification wrapper for Superagnt's documented API, but users should treat the returned work-email data as personal data and use it only where they have authorization.

Before installing, confirm you trust Superagnt with your API key and lookup inputs, and use the tool only for lawful, authorized business-contact workflows. Avoid bulk collection or outreach unless you have an appropriate basis and comply with applicable privacy and anti-spam rules.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding
The skill is explicitly designed to discover and verify work email addresses and list domain-associated emails, which involves privacy-sensitive personal/contact data. While this is the intended function, the documentation omits any guidance on lawful basis, consent, acceptable use, retention, or handling of personal data, increasing the risk of misuse for scraping, profiling, or unsolicited outreach.
