Security audit

tl;dw - YouTube Video Summarizer

Security checks across malware telemetry and agentic risk

Overview

This YouTube summarizer is purpose-aligned, but it under-explains sensitive browser-cookie handling and weakens TLS certificate checks by default.

Review before installing. Prefer public YouTube videos without cookies. If cookies are needed, treat the cookie file like a password, keep it outside shared or synced folders, avoid committing it, delete it after use, and consider restoring certificate verification before using authenticated sessions.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The skill instructs users to export and store authenticated browser cookies to access restricted content, but it does not warn that such cookies are highly sensitive credentials that can enable account/session hijacking if exposed. In an agent skill context, encouraging placement of cookie files in the skill directory increases the chance they are mishandled, logged, cached, or inadvertently shared with other tools.
