Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward SkillBoss-backed web scraper that discloses its API-key and network-service use, with no hidden persistence or unrelated behavior found.

Install only if you are comfortable sending requested URLs and scrape results through SkillBoss API Hub using your SKILLBOSS_API_KEY. Avoid using it for private intranet pages, regulated data, or URLs containing tokens unless SkillBoss handling and retention terms are acceptable to you.

A.I.G

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
88% confidence
Finding
The skill declares that it requires an environment variable containing an API key, but it does not declare any explicit tool scope or permissions boundary. This can mislead operators about what the skill can access and increases the risk of over-broad execution in agent runtimes that rely on manifest metadata for isolation or approval.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill presents itself as a web scraper but does not clearly disclose that user-supplied URLs and fetched page content are transmitted to an external third-party service, SkillBoss API Hub. This creates a data exfiltration and privacy risk because users may pass sensitive internal URLs, tokens in query strings, or confidential page content without realizing it leaves the local environment.
