Video Generation

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed, Markdown-only video planning and generation skill with minor usability cautions around broad triggers and file output.

Installers should expect this skill to guide video scripts or related generated files in Chinese by default. Confirm where files will be written before letting an agent save output, and be aware that the unusual 'meta-skill-system' trigger may be broader than necessary.

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
96% confidence
Finding

The trigger list includes very broad, generic phrases such as '生成视频', '创建视频', and especially 'meta-skill-system', which can cause the skill to activate in contexts the user did not clearly intend. Over-broad activation increases the chance of incorrect routing, prompt hijacking via accidental invocation, or the model following this skill's file-writing instructions during unrelated requests.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

This markdown file is entirely framed as a Chinese-language template, with section titles, task goals, execution steps, and output examples all specified in Chinese. Because the file provides no opt-in, alternative language handling, or justification that the skill is region-specific, it can violate a language/locale policy requiring user choice rather than forced language defaults.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

In the teaching-video example, the narration requirement specifies "标准普通话" and a fixed speaking format as the expected output. This imposes a specific language/locale choice in natural-language instructions without user opt-in or a documented region-specific justification.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The entire template is written in Chinese and presents task goals, steps, and output examples only in Chinese, with no indication that users may choose another language. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The entire skill reference is written only in Chinese, with no indication that users may choose another language or that the skill is intentionally limited to a Chinese-language or region-specific context. Under the stated policy, a language or locale restriction without opt-in or justification is a natural-language policy concern.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The document title and core instruction are entirely in Chinese and explicitly direct the workflow in that language context, but there is no indication that users may choose another language or that the skill is intended only for a Chinese-language environment. This creates a natural-language locale policy concern because the file effectively fixes the interaction/output language without opt-in.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill instructs the agent to save generated content as files and report file locations, but it does not require explicit user consent, destination confirmation, or a warning that file creation will occur. In an agent environment with write capabilities, this can lead to unexpected filesystem changes, accidental overwrites, or creation of artifacts the user did not intend to persist.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

The entire template is written as a Chinese-only skill exemplar and does not indicate that users may choose another language or locale. Under the policy rule for language/locale constraints, this can be treated as a natural-language policy issue when no opt-in or justification is provided.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

This markdown file contains natural-language instructions and examples exclusively in Chinese, which can amount to a language/locale policy constraint if users are not given an opt-in or alternative language option. The file does not state that it is intended only for a Chinese-language or region-specific workflow, nor does it offer language selection.
