Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed company/stock summary helper with bounded inputs and no artifact-backed evidence of hidden access, persistence, or destructive behavior.

Install this if you want a Chinese-language company/stock snapshot skill. Review that it may be implicitly invoked for matching finance questions and that it returns market, valuation, growth, quality, and shareholder data through the Winmale skill runtime; it does not appear to trade, modify accounts, install code, persist data, or read local credentials.

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

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The file’s user-facing name, description, and operating instructions are all presented only in Chinese, and there is no statement that the skill is region-specific or that users may opt into another language. This can violate language/locale policy when a skill implicitly forces one language without user choice.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest description is written entirely in Chinese and presents the skill as operating in that language, with no indication that users may choose another language or locale. Under the policy for natural-language violations, a skill that imposes a language without user opt-in should be flagged unless the locale restriction is explicitly documented and justified.

Vague Triggers

Category

Confidence
94% confidence
Finding

The skill enables allow_implicit_invocation without any visible trigger restrictions or narrowing conditions, so the platform may auto-select this skill in broader contexts than intended. Because this skill appears to provide company analysis and market/valuation information, ambiguous activation could cause unintended use, prompt-routing mistakes, or leakage of user context into the wrong skill execution path.

Natural-Language Policy Violations

Medium
Category

Confidence
90% confidence
Finding

The manifest presents the skill name, description, category, summary, and sample prompts entirely in Chinese, which implies a fixed language/locale for user interaction. The file does not offer an alternative language option or document that the skill is intentionally limited to Chinese-speaking users for a justified regional purpose.
