Security audit

Simple RSS news feed

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward RSS news fetcher, with network access that fits its stated purpose.

Install this if you want an agent helper that fetches live headlines from external news RSS feeds. Be aware it will make outbound requests to the listed news/feed providers when used; no API keys, local data reads, persistence, or privileged actions were observed.

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
Vulnerability Patterns

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill invokes a Python script that performs outbound HTTP requests to multiple third-party RSS feeds, but the manifest does not declare any explicit tool scope or network permission boundary. This creates a transparency and governance gap: a caller or platform may not realize the skill reaches external services, making review, sandboxing, and policy enforcement harder.

Vague Triggers

Confidence

Finding

The 'When to Use' section includes very general phrases such as 'latest news,' 'current events,' 'what's happening in the world,' and 'morning briefing.' These are common conversational requests and the file does not provide narrowing constraints or negative examples, so the skill could be invoked more broadly than intended.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill description says it uses HTTP and RSS feeds, but it does not clearly warn users that invoking the skill sends outbound requests to third-party news providers. This weakens informed consent and can surprise users in privacy-sensitive or restricted-network environments, especially when a simple query like 'latest news' causes external traffic.
