Security audit

Demo Video Creator

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it records browser demos and encodes them into videos, with the main caution being that recordings can capture sensitive on-screen data.

Install only if you are comfortable letting the skill control and record a browser session for demos. Use demo accounts or sanitized data, review captured frames before sharing, and be careful with the configured output directory because the recorder removes and recreates it before saving frames.

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

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: This skill explicitly guides users to capture browser frames and encode them into videos, but it omits any warning that the recorded application may display secrets, PII, internal dashboards, tokens, or other sensitive on-screen content. Because demo recording is often performed against real environments, users may inadvertently create durable artifacts containing sensitive data that can then be shared, stored, or published.
