Overview
yt-dlp is an A youtube-dl fork with additional features and patches
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via improper validation of input in the --write-link, --write-url-link, and --write-desktop-link options. An attacker can achieve arbitrary command execution by crafting malicious webpage_url or filename metadata that, when used to generate shortcut files, injects harmful URIs or desktop entry keys. This can result in execution of attacker-controlled commands if a user opens the generated shortcut file.
