Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese daily-trending fetcher that uses public tophub.today pages and does not show hidden, persistent, destructive, or credential-related behavior.

Install this if you want Chinese-language daily hot-topic summaries. Be aware that invoking it may fetch public pages from tophub.today, and its instructions prefer terse Chinese output without source labels, so users should verify important news separately.

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
Category
Not specified by scanner
Confidence
92% confidence
Finding

The trigger phrases include generic terms like “热榜” that can easily match ordinary user conversation and cause the skill to activate unexpectedly. Over-broad activation can route unrelated prompts into external-fetching behavior, creating unintended network access and reducing user control over when the skill is invoked.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
78% confidence
Finding

The manifest description, instructions, and required output format are entirely in Chinese and mandate a Chinese output style, but the file does not state that this is a China-specific skill or give users any language/locale option. Under the policy rule, forcing a specific language without opt-in is a natural-language policy concern.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

The skill instructs the agent to fetch data from a third-party site without disclosing that user requests may trigger network access. Even if the data is public, silent external requests can surprise users, leak request metadata, and expose the agent to untrusted remote content from the fetched site.
