Security audit

校车运行与安全检查记录核对(免费版)

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local school-bus record checker with disclosed limits and no evidence of hidden network, persistence, or destructive behavior.

Install only if you are comfortable running a local Node script over school-bus records and using a Chinese-header table format. The tool does not verify official records online and its free version intentionally omits several safety checks, so its output should be treated as a record-consistency aid rather than a compliance determination.

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 Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • 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

Finding

The skill uses 'env' capability that is not listed in its permissions. This may indicate deceptive intent or missing permission declarations.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The file’s natural-language contract, warnings, and user-facing messages are written entirely in Chinese, and the parser only recognizes Chinese labels and allowed result values. There is no opt-in, fallback, or documented justification that this skill is limited to a Chinese-speaking or China-specific deployment context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The file's natural-language interface, help text, status messages, and usage guidance are entirely in Chinese, with no indication that users may choose another language or locale. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The inline comment says non-JSON input is treated as plain-text material, giving the example '直接粘贴的合同全文' (full contract text). That contradicts this skill's documented intent of checking school-bus operation and safety inspection records, because it describes handling an unrelated document type.
