Security audit

Dingding

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed DingTalk notification helper that sends user-provided messages through a user-provided webhook and does not show hidden or unrelated behavior.

Before installing, confirm you are comfortable giving the agent access to the DingTalk webhook URL and optional signing secret. Use a narrowly scoped robot, prefer DingTalk signing or IP restrictions, avoid sending sensitive markdown files unless intended, and require confirmation before using @all or posting to large groups.

Finding
The skill describes and encourages use of capabilities that access environment variables and perform outbound network requests, but it does not declare corresponding permissions. Undeclared capabilities weaken auditability and sandbox/policy enforcement, which can let an agent use secrets such as webhook URLs or signing secrets and send data externally without clear user visibility.
