Stock Daily Brief

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language stock briefing skill with no executable code, persistence, credential handling, or hidden behavior.

Before installing, understand that this skill is oriented toward Chinese-language stock briefings and may ask for holdings such as ticker, cost, and quantity. Treat any buy/sell/hold suggestions as informational support, not financial advice.

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

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest description and the entire user-facing markdown content are written in Chinese, and the example invocations are also Chinese-only. Under the policy rule, forcing a specific language without user opt-in can be a natural-language policy violation unless the locale constraint is explicitly justified, which is not stated here.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The package description is written only in Chinese ("股票每日简报生成器"), which may imply a fixed language/locale without any stated opt-in or justification. Under the policy rule, language constraints should either offer user choice or clearly document that the skill is intentionally region- or language-specific.
