Feishu Meeting Assistant

Security checks for vulnerabilities and agentic risk

Overview

The skill does what it says, but it automatically reads meeting-linked Feishu documents and sends derived content while exposing document identifiers and rendering untrusted Markdown without safeguards.

Review this before installing if your Feishu calendar or linked documents may contain confidential material. It should ideally add explicit consent or confirmation, avoid logging or sending raw document tokens, and sanitize or plain-text render calendar and document content in briefing cards.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill description states that it scans calendar events, reads attached Feishu documents, and sends a summarized briefing card, but it does not clearly warn users that potentially sensitive document contents will be automatically accessed and retransmitted. This creates a transparency and consent problem: users may invoke the skill without realizing it processes confidential meeting materials and redistributes derived content to another channel.
