Security audit

Dingtalk

Security checks for vulnerabilities and agentic risk

Overview

This skill only provides guidance for summarizing public DingTalk pages and does not include code, credentials, persistence, or privileged actions.

This appears reasonable to install for summarizing public DingTalk share, app, announcement, or group-invite pages. Users should avoid using it for private enterprise DingTalk content, account actions, messaging, admin tasks, or anything requiring authentication, because the skill does not define those capabilities.

A.I.G

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

Finding
The trigger description is broad enough to activate on many generic DingTalk-related requests, which can cause the agent to invoke this skill when a narrower or safer tool would be more appropriate. Even though the skill claims it only handles public pages, overbroad routing increases the chance of unintended web access, data extraction, or user confusion about the skill’s scope.
