mk-youtube-get-channel-latest

The package implements legitimate functionality for fetching YouTube channel content and caching partial metadata. There is no direct evidence of malicious code in the provided fragment. However, there are notable supply-chain and local execution risks: (1) automatic network download and execution of yt-dlp/jq without documented integrity checks, (2) executing an external shell script with user-controlled arguments (possible command injection depending on script content), and (3) writing predictable files to /tmp which can be tampered with by other local users. Before deploying in sensitive environments, review the shell script implementation and the installer/downloader behavior, add integrity verification for third-party tools, and move metadata storage to a safer location with restrictive permissions.
