Dify Knowledge Base Search

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward Dify knowledge-base search integration that uses a configured API key and endpoint to list and search datasets.

Install this only if you trust the Dify instance configured in DIFY_BASE_URL and are comfortable letting the agent send search queries there using DIFY_API_KEY. Use a least-privileged Dify key, prefer HTTPS for remote endpoints, and avoid sending secrets or regulated data in queries unless that Dify environment is approved.

Finding
The skill clearly requires environment variables and makes outbound API requests to a configurable Dify endpoint, but it does not declare permissions for those capabilities. That creates a trust and policy gap: users or orchestrators may approve or run the skill without understanding that it can access secrets and send data over the network, including potentially sensitive queries and retrieved context.
