CVE-2026-50574 (opens in a new tab)How to fix?
Upgrade yt-dlp to version 2026.6.9 or higher.
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 insufficient sanitization of input passed to the aria2c external downloader. An attacker can achieve arbitrary file writes and potentially execute code by crafting malicious manifest files or metadata that inject options or URIs into the aria2c input file. This can result in immediate code execution on Windows platforms or on subsequent runs on other platforms.
Note: This is only exploitable if aria2c is used as an external downloader for fragmented manifest formats, or if the user disables filename sanitization with the --no-windows-filename option.
Workaround
This vulnerability can be mitigated by adding --downloader dash,m3u8:native to the yt-dlp command.
