Emergence Render Image

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently renders diagrams through a disclosed external Emergence Science API using a user-provided API key.

Install only if you are comfortable sending diagram source to Emergence Science's hosted API with your EMERGENCE_API_KEY. Avoid putting secrets, private business data, or unreleased proprietary details inside diagrams unless that third-party processing is acceptable for your use case.

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

Missing User Warnings

Confidence

Finding

The skill explicitly instructs agents to send user-provided diagram source and an API bearer token to a third-party remote service, but it does not clearly foreground the privacy and data-handling implications to users. This creates a real data exposure risk because sensitive prompts, proprietary diagrams, or embedded secrets could be transmitted off-box without informed consent or adequate warning.

External Transmission

Category
Data Exfiltration
Confidence
88% confidence
Finding

This skill is designed around external transmission to https://api.emergence.science/tools/render, which means user-supplied content and metadata leave the local environment and are processed by a remote service. In this context the transmission is functional rather than overtly malicious, but it still expands the trust boundary and can expose sensitive information, API credentials, or proprietary content if users treat the tool as local-only.
