Feishu Parallel Dispatch

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Feishu workflow helper that spawns background child tasks for longer requests so the chat stays responsive.

Install this only if you want Feishu chats to hand longer requests to background child sessions automatically. Users should expect asynchronous follow-up messages and should explicitly ask for a synchronous answer when they do not want a task spawned.

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

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The skill hardcodes Chinese acknowledgement examples as the prescribed foreground reply pattern, which can override the user's language preference and cause confusing or inappropriate responses in multilingual environments. While not a direct security exploit, it can degrade trust, create miscommunication, and violate expected interaction boundaries when the user did not opt into Chinese output.
