Performance Tester

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward external API guide for generating performance-testing career roadmaps, with a privacy note users should consider before sending identifiers or assessment data.

Before installing or using this skill, treat it as a third-party API integration: avoid sending real names, unnecessary user IDs, sensitive employment details, or internal training data unless you are comfortable with the provider's data handling terms.

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

Finding

The skill explicitly describes collecting assessment data tied to current experience, skills, goals, session identifiers, and timestamps, but provides no privacy notice, retention guidance, minimization advice, or warning about handling potentially identifying data. This creates a real privacy and compliance risk because integrators may transmit personal or behavioral data to a third-party service without informed consent or appropriate safeguards.

Missing User Warnings

Category
Not specified by scanner
Confidence
95% confidence
Finding

The sample request includes sessionId, userId, and timestamps, which can be identifying or linkable metadata, yet the documentation presents them without any caution about privacy, consent, or secure handling. Example payloads strongly influence implementation, so this omission can lead downstream users to send unnecessary identifiers to an external API by default.

Finding

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