DailyExpenseTracker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a real expense-tracker integration, but it can send and modify sensitive financial records through an external API with broad activation and limited confirmation guidance.

Review this before installing if you use DailyExpenseTracker with real financial data. Only install it if you are comfortable storing a DET token in OpenClaw config and sending transaction details and balance queries to the DailyExpenseTracker API; prefer using it only after explicit requests such as recording a specific expense or checking a DET wallet.

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

Vague Triggers

Medium
Confidence
92% confidence
Finding
The trigger description is broad enough that the skill may activate on general mentions of expenses, spending, transactions, or wallets without clear user intent to use this specific third-party integration. In a financial context, unintended invocation increases the chance of sending sensitive financial data to an external API when the user only wanted advice, analysis, or local assistance.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill documents direct use of an external financial service but does not warn that transaction details, balances, wallet names, and other financial metadata will be transmitted off-platform. Without a disclosure and consent expectation, users may unknowingly expose sensitive personal financial information to a third party.

External Transmission

## Add Expense

```bash
curl -X POST "https://dailyexpensetracker.in/api/transactions" \
  -H "Authorization: Bearer $DET_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
Confidence
97% confidence
Finding
This skill explicitly sends financial transaction data to an external API, including amount, date, wallet, category, and description. While this is core functionality rather than obviously malicious behavior, it is security-relevant because external transmission of sensitive financial data can create privacy, compliance, and unintended disclosure risks if invoked without clear consent and safeguards.
