Daily Review Editor

Security checks for vulnerabilities and agentic risk

Overview

This is a narrowly scoped Chinese Markdown editing skill for turning digest candidates into a daily review, with no executable code or hidden high-impact behavior found.

Install this if you want a strongly opinionated Simplified Chinese Daily Review format. Be aware it will steer output into six fixed sections and Chinese summaries for English sources, but it does not add code, background tasks, credential use, or automatic FreshRSS state changes.

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

Confidence
96% confidence
Finding

The instruction "以简体中文工作" forces a specific language for the skill's operation. Under the policy, locale or language requirements should either be optional for the user or clearly justified as region-specific; this file provides neither.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

Lines L71-L72 state that when content comes from English originals, the review 'must provide a Chinese summary.' This is a natural-language locale requirement that forces a specific output language without user opt-in or a documented region-specific justification.
