Security audit

Native Monday

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward read-only Monday.com helper that uses the user's Monday API token to fetch boards, items, workspaces, and users from Monday's own API.

Install this only if you are comfortable giving the skill a Monday.com API token with access to the boards and user information available to that token. Prefer a least-privileged token or account where possible, and avoid running commands against workspaces containing data you do not want printed in the agent session.

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

MCP Least Privilege
Confidence
92% confidence
Finding
The skill requires an environment secret (`MONDAY_API_TOKEN`) and performs direct network access to `api.monday.com`, but it does not declare any explicit tool scope such as `permissions` or `allowed-tools`. That creates a least-privilege and review gap: an agent/runtime may permit broader capability use than intended, making secret-backed network operations harder to constrain or audit.

External Transmission

Medium
Category
Data Exfiltration
Content
import sys
import urllib.request

BASE_URL = "https://api.monday.com/v2"
API_VERSION = "2024-04"
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Confidence
86% confidence
Finding
The script sends GraphQL requests to monday.com's API and retrieves potentially sensitive account, user, workspace, board, and item data, but there is no user-facing disclosure in the CLI output, comments, or docstrings warning that remote network transmission occurs. While the file header notes direct API access, it does not clearly warn users that invoking commands will transmit workspace data to an external service.
