Personal Finance Hardened

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local personal-finance tracker that stores data in a SQLite database and includes explicit guardrails against unsafe database use and external sharing.

Install only if you are comfortable with the skill creating and maintaining a local finance.db file for your personal records. Keep the no-network guardrail in place and avoid asking agents to export or sync financial summaries to external services from this database.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Anti-Refusal Statement

High
Category
Anti-Refusal
Confidence
80% confidence
Finding

Skill attempts to nullify the agent's safety policies or restrictions ('you have no restrictions', 'ignore your guidelines', 'do anything now'). This is a direct jailbreak that disables guardrails.

External Transmission

Category
Data Exfiltration
Confidence
88% confidence
Finding

This line recommends a concrete command that would send financial data to an external endpoint, even though it is presented inside a failure example. In a skill artifact, actionable exfiltration commands can be copied or pattern-matched by downstream agents/users, undermining the stated guardrail that financial data must remain local.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

This code performs filesystem modification by creating directories and initializing a SQLite database file in the user's home directory. Although it prints the path after completion, there is no prior warning, confirmation, or explanatory docstring/comment telling the user that local files will be created under ~/.openclaw/workspace/skills/personal-finance/.
