Lark CLI Dev Hub Sheets
Security checks for vulnerabilities and agentic risk
Overview
This skill is a small Markdown guide for using Lark/Feishu Sheets through a user-authorized CLI, with no bundled executable code or hidden behavior found.
Install only if you intend agents to use lark-cli with your Lark/Feishu account. Review sheet URLs, ranges, and local JSON files before allowing append, dropdown, or export commands, because those actions can read or change office data under your user authorization.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- 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
