Security audit

code-reviewer

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward code-review skill with no executable payload, persistence, hidden data flow, or privilege escalation instructions.

Before installing, expect this skill to guide code reviews and produce prioritized Markdown findings, likely in Chinese unless the user asks otherwise. For sensitive repositories, explicitly state the files or modules to review.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger description is very broad (e.g., any request about code review, code quality, code checking, optimization) without clear boundaries on repository scope, file access, or task limits. In an agent environment, this can cause over-invocation or application to unintended inputs, increasing the chance of excessive data exposure or unsafe autonomous actions on sensitive codebases.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill content is entirely specified in Chinese and describes the deliverable and workflow only in that language, without indicating that users may choose another language. This creates a locale/language constraint without explicit opt-in or documented justification.
