Security checks for vulnerabilities and agentic risk

Overview

This skill is not malicious, but it can post to a user's Knowledge Planet account without a clear final approval step.

Review this skill before installing if you plan to use it for posting. It should only be used when you explicitly intend to operate zsxq.com, and you should require the agent to show the final post content and get your approval immediately before publishing.

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

Missing User Warnings

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill explicitly instructs the agent to publish posts directly and says screenshots are not needed, but it does not require an explicit user confirmation immediately before the final publish action. In an automation context, this creates a real risk of unintended or manipulated content being posted under the user's account, especially after the user has already authenticated.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger phrases are broad enough that the skill may be invoked for loosely related requests such as general posting, login help, or content viewing, increasing the chance of unintended activation. Because this skill can perform authenticated actions on a third-party platform, accidental invocation could lead to navigation, login prompting, or posting actions in the wrong context.

Finding

This shell script's natural-language comments and echoed output are entirely in Chinese, with no indication that the user can choose another language or that the locale restriction is intentional. The policy explicitly calls for flagging language or locale constraints when they are forced without user opt-in.
