Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped DingTalk table helper for saving and looking up U.S. stock analysis reports, with no hidden code or persistence beyond the intended table records.

Before installing, confirm that the listed DingTalk Base ID and Sheet ID are the table you intend to use, and that you are comfortable storing stock analysis summaries and document links there via the dingtalk-ai-table integration.

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

Findings (1)

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The manifest description and the entire skill instructions are written in Chinese and prescribe user-facing behavior such as querying and displaying results, but there is no indication that language choice is optional. Under the policy, forcing a specific language or locale without user opt-in is a natural-language policy violation unless clearly justified as region-specific.
