Security audit

Flower

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent Flower project-management integration, but it asks users to run an unpinned npm MCP server with an API token and exposes live delete/member-management actions without safety guidance.

Before installing, pin and review the MCP package version, use a narrowly scoped Flower token, avoid exposing unrelated environment secrets to the MCP process, and require explicit confirmation before delete, remove-member, or bulk update operations.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

MCP Rug Pull
Confidence

Finding

The skill instructs users to execute an MCP server directly from npm via npx -y @xferops/flower-mcp without pinning an exact version or integrity. That creates a supply-chain risk: a future compromised or malicious package release would be fetched and executed automatically, and because this server is configured with a Flower API token, compromise could expose credentials or enable unauthorized project/task operations.

Missing User Warnings

Confidence

Finding

The skill documents destructive capabilities such as deleting tasks, columns, comments, and removing team members, but provides no warning, confirmation guidance, or guardrails. In an agent-assisted workflow, this increases the chance of accidental or over-broad destructive actions, especially because the connected MCP server operates against live project-management data using an authenticated token.
