Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent but should be reviewed because it can publish directly to a user's Weibo account without a clear mandatory confirmation step.

Install only if you are comfortable with an agent using your logged-in Weibo browser session. Before use, verify the exact account and post text, and require an explicit final confirmation before the agent clicks send.

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

Confidence

Finding

The trigger phrases include broad natural-language requests like '帮我发微博', which can match common conversational text and increase the chance of unintended activation. Because this skill performs an external side effect—publishing to a social-media account—accidental triggering can cause unauthorized or embarrassing posts, and the post may be difficult or impossible to fully retract.

Missing User Warnings

Confidence
91% confidence
Finding

The skill description says it posts to Weibo but does not prominently warn users about the privacy, account, and irreversibility implications of submitting content to an external public platform. In this context, weak disclosure is risky because the workflow directly automates browser actions to publish content, and users may not realize the action is public and not easily undoable.
