Dingtalk Csa

Security checks across malware telemetry and agentic risk

Overview

This DingTalk document skill appears purpose-aligned, but it includes write-capable examples that can overwrite enterprise documents without strong guardrails.

Review before installing. Use only with least-privilege DingTalk credentials, restrict write access to disposable or approved folders, and do not run the overwriteContent examples on real documents unless you have a backup and explicit approval from the document owner.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The guide includes a live verification command that calls an overwriteContent endpoint against an existing document ID, which will modify remote data if a user substitutes real values and runs it. Because the example is presented as a routine permission test without an explicit destructive-action warning or safer alternative, it can cause accidental content loss or document corruption.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The trigger description is broad enough to match generic file analysis, report generation, and collaboration requests, which can cause the skill to activate in situations beyond explicit DingTalk cloud-storage operations. In an agentic environment, over-broad routing increases the chance of unintended access to enterprise file data or write-capable tooling being invoked for loosely related prompts.
