Security audit

Daily Report Writer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small user-invoked helper that writes a daily report draft to a clearly named local reports file.

Install this if you want a Chinese daily-report drafting helper that writes Markdown files under reports/. Review the generated file path before use if you already keep important files in that directory, because the artifact does not define overwrite handling in detail.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The natural-language content of the skill is entirely in Chinese and the description specifies generating a daily report draft in that context, but there is no indication that users may choose another language. Per the policy, forcing a specific language without user opt-in is a natural-language policy concern unless the locale restriction is explicitly justified.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly states it will read or create and then write reports/{{date}}-daily-report.md, but it does not clearly warn the user that invoking the skill modifies files on disk. This can lead to unintended local file changes, especially in agent contexts where users may assume a draft is only generated in-memory unless persistence is disclosed.
