Security audit

social-media-scraper

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed public social-media scraping connector with some privacy and supply-chain cautions, but no hidden or destructive behavior in the artifact.

Install only if you are comfortable sending target handles, URLs, search queries, and returned public social-media data through ToolRouter. Do not use it for private accounts, sensitive personal-data collection, harassment, doxxing, or activity that violates platform terms; consider pinning or reviewing the MCP package before using the npx connector.

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 skill is explicitly designed to collect and return social media profiles, posts, comments, media URLs, and engagement data across many platforms, but it does not include meaningful privacy, retention, consent, or downstream-use guidance. Even when data is public, bulk aggregation and redistribution can create privacy, compliance, and misuse risks, especially when comments or profile data are processed at scale.

External Transmission

Medium
Category
Data Exfiltration
Confidence
86% confidence
Finding

The skill directs the client to connect to an external MCP endpoint at https://api.toolrouter.com/mcp, which means prompts, targets, and retrieved social media data may be transmitted to a third-party service. This is dangerous if users are not clearly informed what data leaves the local environment or if the remote service is trusted with sensitive queries or output handling by default.

## Installation

Install with `pnpm dlx skills add Humanleap/agent-skills --skill social-media-scraper`. Connect the client's remote MCP server to `https://api.toolrouter.com/mcp` (Claude: Customize → Connectors → Add custom connector; Claude Code: `claude mcp add toolrouter -- npx -y toolrouter-mcp`). Setup: https://toolrouter.com/docs/markdown/quickstart.

Confidence
90% confidence
Finding

The skill instructs users to run npx -y toolrouter-mcp without pinning a specific package version or integrity hash. That creates a supply-chain risk: future package updates or a compromised publisher account could cause users to execute unexpected code when adding the MCP connector.
