Auto-Report

Security checks for vulnerabilities and agentic risk

Overview

This reporting skill is coherent and purpose-aligned, but users should be careful with scheduled delivery because reports can read local data and send it to chat channels.

Before installing or using this skill, confirm each scheduled report's data sources, target chat or document, timezone, and retention expectations. Avoid pointing it at sensitive files or broad channels unless the audience is authorized to see the resulting summaries.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list includes very broad, everyday terms such as "report", "总结", and "standup", which can cause the skill to activate in contexts unrelated to scheduled reporting. In an automation skill that can create cron jobs and send messages to channels, accidental invocation raises the risk of unintended task creation, data access, or message delivery.

Missing User Warnings

Medium
Category

Confidence
92% confidence
Finding

The skill explicitly supports scheduled delivery to chat channels and persistent document creation/updates, but it does not warn users that reports may include sensitive data or be sent automatically to external destinations. Because the skill also encourages reading local files and pushing summaries to channels, this creates a realistic risk of privacy leakage or unauthorized disclosure through automation.

Natural-Language Policy Violations

Low

Confidence
80% confidence
Finding

The examples hard-code the timezone to "Asia/Shanghai", and the schedule reference section repeats that locale as the default without offering alternatives or stating that it is only illustrative. This can conflict with organizational language/locale policies when users operate in other regions.
