Security checks for vulnerabilities and agentic risk

Overview

This Snapchat advertising skill is broad and can automate account actions, but the reviewed artifacts disclose those capabilities and require user approval for sensitive operations.

Install only if you intend to use Maton to manage Snapchat ad resources. Review every write, trigger, destination, and hosted function before approving it, keep event triggers narrowly scoped, and avoid raw API keys unless the CLI is unavailable.

A.I.G

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

Finding

The Snapchat skill's stated purpose is managing Snapchat advertising resources and viewing ad performance, and the manifest explicitly says Snapchat is not an event source and that shared trigger references do not add Snapchat capability. This file nevertheless documents Notion page and comment event monitoring, including workspace-wide content forwarding behavior, which is a capability outside the justified scope of a Snapchat marketing integration.
