Core Vocabulary for CET-4

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple CET-4 vocabulary helper that reads a bundled word list and does not show hidden, destructive, network, credential, or persistence behavior.

Reasonable to install if you want a Chinese-language CET-4 vocabulary helper. Be aware it declares shell availability even though its visible behavior only needs to read the bundled word list; prefer a future version that documents a maximum word count and narrows or explains that shell requirement.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
Findings (5)

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill requests shell access even though its stated function is only to read random entries from a local vocabulary file. Unnecessary execution capabilities violate least privilege and expand the attack surface, enabling file access or command execution beyond what users would reasonably expect from a simple vocabulary skill.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The natural-language instructions require returning Chinese-labeled output and Chinese translations, but do not offer the user any language or locale choice. This is a language policy concern because the skill appears to enforce a specific output language by default rather than allowing user preference.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The invocation instructions say to extract a user-requested number N and randomly read N items, but they do not define clear trigger boundaries, validation rules, or limits. Ambiguous activation and unbounded parameter handling can cause the skill to run unexpectedly or process excessive requests, which is risky when combined with shell-backed local file access.

Natural-Language Policy Violations

Confidence

Finding

This plain-text vocabulary file consistently presents definitions and example translations in Chinese only, which imposes a specific language/locale across the entire skill content. The file does not indicate that Chinese is optional, user-selected, or justified as a region-specific resource.
