MiniMax CLI

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent MiniMax CLI helper, but it asks users to install an unpinned global npm package and shows an API key being passed on the command line.

Review this before installing. Prefer a pinned, verified `mmx-cli` version or a local/project-scoped install, avoid running npm with elevated privileges, and do not paste a live API key directly into a shared terminal or logged agent session. Use a safer authentication flow if the CLI supports it, check permissions on `~/.mmx/config.json`, and monitor MiniMax quota or billing after use.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Findings (3)

Credential Access

High

Category: Privilege Escalation
Confidence: 70% confidence
Finding: Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
Content: Scanner excerpt · SKILL.md (reported line 19)May include surrounding context.
Setup

bash
# Authenticate (get key from https://platform.minimax.io) mmx auth login --api-key sk-xxxxx # Verify

External Model or Provider Selection

High

Category: Excessive Agency
Confidence: 90% confidence
Finding: Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
Content: Scanner excerpt · SKILL.md (reported line 32)May include surrounding context.
Text Chat

bash
mmx text chat --message "prompt" mmx text chat --model MiniMax-M2.7 --message "prompt" --stream mmx text chat --system "You are a helpful assistant" --message "prompt" mmx text chat --messages-file ./conversation.json --output json

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The skill instructs users to pass an API key directly on the command line, which can expose the credential through shell history, process listings, terminal logs, or agent telemetry. While this is common in examples, omitting any warning or safer alternative creates a real credential-handling risk in an agent-oriented skill.
