Security audit

LSP Novel Writer

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Chinese novel-writing helper that creates outline and chapter files, with no evidence of hidden execution or data theft.

Before installing, expect the skill to guide a Chinese web-novel workflow and create one markdown file per chapter under ./novels/小说标题/. Choose or monitor the output folder if storage, filenames, or overwriting existing drafts matter to you.

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
Findings (4)

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger phrases are very broad generic writing requests, so the skill may activate for ordinary brainstorming or editing asks where the user did not intend a multi-step novel-generation workflow. This can cause unintended data collection, workflow hijacking, and downstream file-generation behavior that exceeds user expectations.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The trigger section does not define clear activation boundaries, disambiguation logic, or when the skill should refuse to engage, making accidental invocation more likely. In this context, accidental activation is more dangerous because the skill can transition into automated content generation and persistence to disk.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs automatic chapter-by-chapter saving to the filesystem without a clear upfront warning, explicit user consent for writes, or constraints on write scope. Even though the content domain is benign, silent or assumed file creation can surprise users, consume storage, overwrite existing content, or create unwanted persistent artifacts.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The document title and all instructional content are written entirely in Chinese, with no indication that the skill supports other languages or that Chinese is an intentional, documented locale restriction. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
