Security checks for vulnerabilities and agentic risk

Overview

This Trello skill is a straightforward set of documented API commands, but users should be careful because some examples modify live Trello cards.

Install only if you are comfortable giving the agent a Trello token with the permissions that token carries. Treat create, move, comment, and archive examples as live changes to your Trello account, and prefer a limited-scope or dedicated token if your Trello setup supports it.

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

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill includes multiple state-changing operations such as creating cards, moving cards, adding comments, and archiving cards, but it does not clearly warn users at the point of use that these actions will modify live Trello data. In an agent setting, that increases the risk of accidental or unintended changes to production boards because users may invoke examples without realizing they are write operations.
