Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese-language reconciliation-table checker with no evidence of network access, persistence, credential handling, or hidden behavior.

Install only if you are comfortable running a local Node-based checker on reconciliation-table data. The tool appears to keep processing local and does not require payment, registration, API keys, or network access, but its interface and output are mainly Chinese and its free version intentionally omits several disclosed checks.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Finding

This JavaScript file's user-facing natural-language content is entirely in Chinese, including instructions, warnings, errors, summaries, and disclaimers. Because it does not offer any language selection or document a justified region-specific limitation, it imposes a specific language/locale on users without opt-in.

Natural-Language Policy Violations

Confidence
94% confidence
Finding

The user-facing description, usage text, prompts, and output messages are entirely in Chinese, and there is no indication that another language is supported or that the user can opt into this locale. Under the stated policy, a skill should not force a specific language unless it offers choice or clearly documents a justified region-specific constraint.

Finding

The inline documentation states that invalid JSON will be treated as plain-text material, giving '直接粘贴的合同全文' as the example. That contradicts the skill's stated intent and surrounding help text, which consistently require an intercompany reconciliation table with headers rather than arbitrary contract text.
