Security checks for vulnerabilities and agentic risk

Overview

This skill coherently searches public social posts through a disclosed third-party API and does not show hidden persistence, broad local access, or destructive behavior.

Install this only if you are comfortable sending your search queries to SocialListeningAPI and using credits on that account. Keep the API key in the environment as instructed, review results before acting on them, and limit the agent runtime to the included Node script and the SocialListeningAPI domain where possible.

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

Undeclared Tool Scope

MCP Least Privilege
Confidence

Finding

The skill instructs the agent to execute a Node script and use an API key plus outbound network access, but it does not declare any explicit tool scope such as allowed tools or permissions. That creates a governance gap: an agent runtime may permit broader execution or network behavior than intended, making misuse, prompt-injection chaining, or accidental overreach harder to contain.

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
