MailerLite

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed MailerLite integration that uses Maton authentication and includes clear approval rules for writes, automations, webhooks, and credentials.

Before installing, be aware this skill can affect real email audience and campaign data once you authorize MailerLite. Use OAuth where possible, confirm every write or webhook/automation setup, avoid broad or third-party forwarding unless you explicitly need it, and revoke unused connections or triggers when finished.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
