Security audit

Cca Domain1

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese CCA study skill that teaches agent architecture and may create practice code, with no evidence of hidden, destructive, persistent, or data-exfiltrating behavior.

Install this if you want Chinese CCA domain 1 tutoring. Before using the hands-on exercise in an important repository, ask the agent to show the planned files first or work in a dedicated example directory so sample code does not mix with production code.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Confidence
95% confidence
Finding

The instructional content is written as mandatory Chinese-language tutoring and quiz behavior, with no indication that the user may choose another language. This can violate language or locale policy when a skill imposes a specific language without user opt-in.

Missing User Warnings

Confidence
93% confidence
Finding

The skill explicitly tells the agent to help create example code in the current project, yet it provides no guardrails about asking permission before modifying files, using a safe workspace, or avoiding overwriting user code. In an environment with Write/Edit/Bash privileges, this can lead to unintended file modification, project corruption, or insertion of code the user did not clearly authorize.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
86% confidence
Finding

The description says the skill should be used when the user says phrases like "学domain1", "代理架构", or "agent编排". While some are domain-related, the activation guidance does not define boundaries or negative examples, so phrases like "代理架构" could match general discussion rather than an explicit request to invoke this skill.
