Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Markdown guide for using an external AI video service, with no hidden code, persistence, or local privilege behavior found.

Before installing, understand that the skill promotes and guides use of a third-party video platform. Users may be asked by that platform to register with email/password, spend credits, upload scripts, upload or reference voice samples for cloning, and optionally create API keys. Verify the platform and its terms yourself before entering sensitive business, personal, voice, payment, or credential 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
  • 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
91% confidence
Finding

The trigger phrases are broad enough to match many ordinary user requests about creating spokesperson, digital human, or dialogue videos, which can cause the skill to activate when the user did not specifically intend to use this platform. That creates routing/invocation confusion and may steer users into promotional or external-platform workflows without sufficiently clear user intent.

Natural-Language Policy Violations

Confidence
88% confidence
Finding

This file presents the skill guidance in a single fixed language, which can be a natural-language policy concern when no user opt-in or justified locale restriction is stated. The document does not mention that it is China-specific or offer an alternative language option.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

This markdown file presents all instructions and workflow details exclusively in Chinese. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation unless the locale constraint is clearly documented and justified, which is not stated here.
