Security checks for vulnerabilities and agentic risk

Overview

The skill appears local and purpose-focused, but needs review because one payroll reconciliation claim does not match what the code actually checks.

Install only if you are comfortable running a local payroll checker on sensitive wage and identity data. Do not rely on its NO_ISSUE_FOUND result for special-account payout reconciliation; manually compare net_total and payout_total or use a version that explicitly implements that check.

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

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The file’s natural-language comments and user-facing strings are entirely in Chinese, including instructions, warnings, and result text, with no indication that another language is supported or that the locale restriction is optional. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless clearly justified as region-specific.

Intent-Code Divergence

Confidence
97% confidence
Finding

The skill states it checks aggregate consistency between the wage table and special-account payout records, but the free version does not actually compare net_total against payout_total; it only computes and exposes both values. In a payroll/compliance workflow, this can mislead operators into believing a required reconciliation was performed, causing underpayment, overpayment, or regulatory discrepancies to go undetected.

Finding

The comment states that non-JSON input is handled as plain text material such as '直接粘贴的合同全文', which contradicts the manifest and the rest of the script that consistently require a '建筑工人工资专户发放核对表(含表头)'. This is not merely incomplete documentation: it names a different document type than the code's intended capability and surrounding help text.
