Security checks for vulnerabilities and agentic risk

Overview

This skill locally converts a user-provided article into Chinese social-platform draft formats and does not show hidden posting, network, persistence, or data-exfiltration behavior.

Install this if you want local Chinese social-media draft generation from text you provide. Be aware that the interface and generated copy are Chinese-focused, and review drafts manually before posting because the skill does not check current platform rules or publish for you.

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

Confidence
96% confidence
Finding

The tagline is entirely in Chinese and describes the skill as producing drafts for Chinese platforms, which indicates a language-specific behavior. The manifest does not state that the user can choose another language or that Chinese output is optional, so this appears to impose a locale/language constraint without explicit opt-in.

Natural-Language Policy Violations

Confidence
87% confidence
Finding

The skill’s natural-language description, invocation examples, workflow, and output guidance are written entirely in Chinese, which effectively forces a specific language/locale for use. The policy allows locale constraints only when users are given a choice or the constraint is clearly justified as region-specific, neither of which is stated here.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The file includes its top-level description and usage guidance entirely in Chinese, and later user-facing output and errors are also Chinese-only. Because the skill does not offer language selection or state that it is intentionally limited to a Chinese-only audience, this is a natural-language locale policy concern under the language/locale rule.
