Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only Chinese fortune-telling skill with no code execution, persistence, network access, or hidden data movement.

Install only if you want a Chinese-language symbolic fortune-telling report. Avoid sharing more personal details than needed, especially sensitive family, relationship, photo, health, legal, or financial information, and treat the output as symbolic rather than professional 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill explicitly requires returning a full Chinese report, but there is no requirement to respect the user's language preference or request confirmation. This can reduce transparency and informed consent, especially if a user does not read Chinese well and may miss safety caveats or limits in a high-sensitivity symbolic guidance context.

Missing User Warnings

Confidence
95% confidence
Finding

The skill explicitly directs collection and processing of extensive personal data, including highly sensitive attributes such as birth details, relationship status, family background, photos, and major life events, yet provides no privacy notice, minimization rule, or consent boundary. In a destiny-analysis skill, users may be nudged to reveal more sensitive data than necessary, increasing privacy, profiling, and retention risk.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

The prompt mandates '使用中文' and a fixed Chinese-language advisory style as a universal requirement. This is a natural-language locale constraint, and the file does not provide user opt-in, fallback language choice, or a documented region-specific justification.
