Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent for an internal cloud-phone admin workflow, but it gives broad production data access through browser actions and arbitrary instance file downloads without enough scoping or confirmation.

Install only if users are authorized production operators for this admin platform. Before use, require the agent to confirm the exact instance ID and file path, avoid arbitrary filesystem downloads unless explicitly approved, and treat copied downloads as potentially sensitive production data.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
81% confidence
Finding

The skill description, triggers, warnings, and examples are entirely in Chinese, with no indication that users may interact in another language or that Chinese is required for a region-specific reason. This creates a language/locale policy concern because the skill implicitly constrains interaction language without opt-in.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The trigger phrase for opening instance details is context-poor and can fire on a vague follow-up like '打开实例详情' without verifying that a prior search selected the intended instance. In an admin console for a production cloud-phone platform, this can cause the agent to navigate to the wrong tenant/resource and expose sensitive operational data or set up later unsafe actions.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The download triggers are broad enough to authorize arbitrary file-path downloads from an instance, including direct path-based requests such as '/data/misc/logd/logcat' or other user-supplied paths, without clear scope restrictions or approval gates. In the context of a production operations platform, this creates a real risk of unauthorized retrieval of sensitive logs, device data, secrets, or other filesystem contents from the wrong instance.
