Security audit

Youtube Clip Curator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward YouTube clip-planning prompt with no bundled code, persistence, credential use, or hidden behavior.

Installers should treat this as a content-analysis helper: only provide media or transcripts you have rights to process, avoid confidential/private recordings unless you are comfortable sharing them with the active agent/tools, and specify the desired language or locale if you do not want Japanese-style clip titles or tags.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium
Category

Confidence
89% confidence
Finding

The skill solicits YouTube URLs, MP4 paths, and transcripts, and optionally produces Whisper-derived subtitles, but it does not warn users about privacy, copyright, consent, or local-file disclosure risks. This can lead users to provide sensitive or unauthorized media, creating compliance and privacy exposure even though the skill itself is not overtly exfiltrating data.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The example output and scoring/composition rules strongly bias titles, tags, and emphasis terms toward Japanese text and Japanese clip-culture conventions, but the document never says this is optional or limited to a Japan-specific workflow. That can violate language/locale policy because it effectively forces a specific language style without user opt-in.
