Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Douyin-to-Feishu analysis workflow with expected external writes, and I found no hidden code, persistence, or deceptive behavior.

Before installing, verify the configured Feishu base and table point to the intended workspace, keep API keys in environment variables as instructed, and expect the skill to write records/doc links and potentially download video files when used.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The markdown describes remote write operations to Feishu Bitable and generation/linking of cloud documents, which can affect user data and external system state. While the file notes permissions and rate limits, it does not clearly warn users that running the skill will create or modify records/documents in Feishu.

Finding

The natural-language content of the skill is presented only in Chinese, which may force a specific language on users without opt-in. The policy allows locale constraints when documented and justified, but this file does not explain any language limitation or provide alternatives.
