Security audit

LLM Wiki

Security checks for vulnerabilities and agentic risk

Overview

This skill creates a local markdown wiki and its file reading, writing, and logging behavior is disclosed and aligned with that purpose.

Install only if you want an agent to maintain a persistent local markdown knowledge base. Avoid placing sensitive documents in llm-wiki/raw/ unless you are comfortable with summaries, derived pages, and query logs being stored in the workspace; ask the agent to identify exact files and preview planned wiki changes before ingestion when working in important repositories.

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill states that query interactions are logged, but it does not clearly warn users that ordinary questions may be stored persistently. This can lead to accidental retention of sensitive prompts, internal project details, or personal data in log files that may later be read, synced, or exposed.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The invocation language for processing new sources is broad enough that an agent may ingest and act on any newly added file without clear scoping, confirmation, or trust boundaries. In a skill that reads arbitrary documents and then writes multiple persistent files, underspecified triggers increase the risk of prompt injection from source content and unintended modification of the knowledge base.

Missing User Warnings

Confidence
94% confidence
Finding

The skill says it automatically creates the folder structure and base files on first use, but it does not provide a clear up-front warning that using the skill will modify the workspace. Silent or unexpected file creation can violate user expectations, interfere with repositories, and create persistence that later workflows may trust or consume.
