Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims: it helps extract image frames from user-provided video files into a chosen output folder.

Before installing, understand that using this skill can create many image files from a video. Pick a controlled output folder and use intervals or frame ranges for long or high-resolution videos to avoid unnecessary storage use.

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

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 95% confidence
Finding: This markdown skill describes extracting and saving frames, but it does not explicitly warn users up front that the operation will create many files and can materially affect local storage. Although disk-space requirements and limitations are mentioned later, those are framed as technical requirements rather than a direct user-facing warning about data/system impact.
Content: No source excerpt is available for this finding.
