Security audit

YouTube Channel Videos API

Security checks across malware telemetry and agentic risk

Overview

The skill is a focused YouTube lookup integration, but it exposes the required JustOneAPI token through command arguments and the request URL.

Review before installing. The skill appears limited to the advertised JustOneAPI YouTube endpoint and does not show hidden or destructive behavior, but use a dedicated low-privilege token and avoid environments that log command lines or full URLs. Prefer a revised version that reads the token directly from a protected environment variable or secret store and avoids query-string authentication if the API supports it.

Finding
Passing an access token in a query parameter is dangerous because query strings are commonly logged by clients, proxies, gateways, browser history, and monitoring tools. Even when sent over HTTPS, the token may be exposed through operational logs or referrer-like propagation, increasing the chance of credential leakage and unauthorized API use.
