Security audit

Filament Vault

Security checks for vulnerabilities and agentic risk

Overview

This skill locally manages a 3D-printer filament inventory and does not show hidden network access, privilege changes, or unrelated behavior.

Installers should be comfortable with the skill storing filament inventory details, notes, locations, and purchase costs in a local JSON file under the OpenClaw workspace. Review the broad trigger wording if you want the skill to activate only for explicit inventory-management requests.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding

The skill advertises local file read/write behavior but does not declare any explicit tool scope or permissions boundary. That makes its filesystem access implicit rather than constrained, increasing the risk of overbroad access or accidental misuse if the runtime grants more capability than the documentation suggests.

Vague Triggers

Category
Not specified by scanner
Confidence
89% confidence
Finding

The 'Use when' list includes generic phrases such as 'filament', 'what filament do I have', and 'printing materials', which are broad enough to match everyday user requests outside a clearly bounded invocation context. The manifest does not provide negative examples or explicit scope constraints to distinguish when this skill should or should not activate.
