Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward WeChat article-writing helper with optional user-directed document export and no hidden code or credential access.

Before installing, users should know that generated article drafts, image-plan files, and exported Word documents may be saved locally if they choose those options. Review generated marketing or public-account content for accuracy and avoid including sensitive private information in drafts unless the workspace is trusted.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The description says the skill is invoked whenever a user needs to create a WeChat public-account article, but it does not define specific trigger phrases, scope boundaries, or exclusion conditions. This broad natural-language condition could overlap with many ordinary writing requests and cause unintended invocation in loosely related content-generation contexts.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The instruction explicitly requires that image prompts be written in Chinese, which imposes a language choice on users. There is no opt-in, alternative language option, or documented regional necessity that would justify forcing a single language.

Missing User Warnings

Low
Category

Confidence
91% confidence
Finding

The skill describes creating files and exporting documents as if they are saved directly, but it does not require an explicit user warning or confirmation about writing to disk at the moment of file creation. In environments with file-system tools, this can cause unintended local persistence of user content, surprising the user and potentially exposing sensitive drafts or generated material to later access.
