News Sentiment免费版

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language stock news sentiment analysis skill with no bundled executable code and no evidence of hidden, persistent, destructive, or exfiltrating behavior.

Before installing, note that this free skill is documentation-only in the submitted package and may not work as written because the referenced Python script is not included. Use it for informational sentiment summaries only, not investment advice, and avoid providing private credentials beyond any API key you intentionally configure for your agent environment.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Confidence
84% confidence
Finding

The skill metadata forces Chinese-language presentation via displayName and Chinese-first content without indicating user choice or locale negotiation. While not directly enabling code execution, hard-coded language behavior can cause misleading outputs, reduce operator comprehension, and increase the risk that users approve actions or results they do not fully understand.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The description is extremely broad and generic, stating the skill is suitable for general development scenarios and can be driven by natural-language instructions, without defining tight activation boundaries. In an agent environment with exec enabled, vague scope increases the chance the skill is invoked in unintended contexts or used to justify arbitrary command execution beyond news sentiment analysis.
