Breached Email Check

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward breach-check integration, but users should understand that checked email addresses are sent to ToolWeb.in.

Install only if you are comfortable sending the email addresses you check to ToolWeb.in's breach-check service. For employee, customer, or other third-party addresses, use it only under an approved security workflow with proper consent and data-handling review.

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

Missing User Warnings

Finding
The skill encourages submitting arbitrary email addresses to a third-party breach-check service but does not clearly warn users that the address will be transmitted externally and may constitute personal data. This creates a privacy and compliance risk because users may unknowingly send employee, customer, or other sensitive identifiers to an external provider without consent, approval, or data handling review.
