Reminder

Security checks for vulnerabilities and agentic risk

Overview

This reminder skill is purpose-aligned and discloses local persistence, but the package only contains documentation and no executable reminder script.

Before installing, treat reminder messages and schedules as locally persisted data in ~/.openclaw/reminders.json, avoid storing highly sensitive details on shared or backed-up machines, and verify any separate reminder.py implementation before running the documented commands because it is not included in this package.

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

Session Persistence

Medium

Rogue Agent
Confidence
80% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill explicitly states that reminders are persisted to a local file, but it does not warn users that reminder contents may include sensitive personal or business information and will remain on disk across restarts. This creates a real privacy risk on shared, backed-up, or compromised systems because reminder text and schedules can be recovered later.
