Security audit

Wework

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed WeCom group-message helper that sends user-chosen text or files through a webhook.

Install this only if you want agents to send messages or attachments to a WeCom group. Treat WECOM_WEBHOOK_KEY as a secret, scope it to the intended group robot, and review any markdown, image, or file path before sending because that content will be transmitted to WeCom.

Finding
The skill documents and encourages use of environment variables and outbound network access, but it does not declare corresponding permissions. This creates a transparency and least-privilege problem: an agent or reviewer may not realize the skill can access secrets from the environment and send data to external services, which increases risk of unintended secret exposure or unauthorized exfiltration.
