Video Compressor

Security checks for vulnerabilities and agentic risk

Overview

This skill mainly provides guidance for using an external video-compression website and includes only simple local scripts that print that guidance.

Before installing, understand that the skill sends you to VideoAny's website and any uploaded videos are handled by that third-party service. Use it only for videos you are authorized to process, and avoid sensitive footage unless you are comfortable with that site's handling of uploads.

A.I.G

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

Finding

Declared permissions with no matching code capability may indicate removed functionality or pre-staging for future abuse.

Finding

The file name and backward-compatibility framing imply this script is a legacy entrypoint for video dubbing, but the actual implementation imports and executes guide_video_compressor.main. The warning text confirms the script now serves video-compressor guidance instead, so the documented/implicit intent of the entrypoint contradicts its current behavior.
