Security checks for vulnerabilities and agentic risk

Overview

This is a small personal finance skill with disclosed local storage and no bundled executable or hidden behavior in the inspected artifact.

Before installing, confirm you are comfortable storing income, expense, and budget data in local JSON files under ~/.memory/finance, and only run the referenced Python script if it comes from a source you trust because it was not included in this artifact.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The natural-language description, headings, and usage guidance are presented in Chinese, which can impose a language constraint on users without any explicit opt-in or justification. Per the policy, forcing a specific language without user choice is a natural-language policy violation unless the locale limitation is documented and justified.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill explicitly stores financial records and budget data in persistent local files under the user's home directory, but the description does not warn users about this persistence. For a finance-related skill, silent storage of sensitive spending and income data can create privacy and data-retention risks if users assume the data is ephemeral.
