Cnki Exp Search Automation

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed CNKI literature-search helper that uses browser automation to collect article metadata and does not include hidden execution, persistence, or credential-handling behavior.

Before installing, be aware that the skill automates CNKI in a browser and may use your logged-in browser profile to handle CAPTCHA or access article details. Use it only where CNKI access is authorized, review exported files before sharing them, and keep request rates reasonable to comply with site terms.

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
  • Tool MisuseTool Parameter Abuse, Chaining Abuse, Unsafe Defaults
  • 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

Tool Misuse
Confidence
75% confidence
Finding

Confidence
93% confidence
Finding

The file consistently presents the skill description, usage, warnings, and operational steps only in Chinese. Under the policy for natural-language violations, forcing a specific language without user opt-in is reportable when no alternative language or explicit choice is offered.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

This markdown file presents all instructions, examples, and labels only in Chinese, including the title and every usage example. Under the policy rule for language or locale constraints, forcing a single language without user opt-in can be a natural-language policy violation unless the regional limitation is clearly documented and justified.
