Security audit

Skill Learner 818d6a

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language guide skill with no executable code, persistence, credential access, or hidden behavior.

Before installing, consider whether the broad triggers could be annoying in normal conversations and whether Chinese-only guidance fits your workflow; there is no evidence of code execution, data access, persistence, or hidden behavior.

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 conditions are very broad because they activate on generic terms like "Hermes" and "skill-learner," which can appear in many unrelated conversations. This can cause unintended skill invocation, leading to context hijacking or inappropriate responses when the user did not actually request this skill.

Natural-Language Policy Violations

Low

Confidence
83% confidence
Finding

The natural-language content of the skill, including its description, steps, and trigger scenarios, is entirely in Chinese with no indication that users may choose another language. This can conflict with language or locale policy requirements when no user opt-in or documented locale restriction is provided.
