There is no fixed version for Debian:12 yt-dlp.
NVD Description
Note: Versions mentioned in the description apply only to the upstream yt-dlp package and not the yt-dlp package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
yt-dlp is a command-line audio/video downloader. Prior to 2026.06.09, if aria2c is used as an external downloader for a fragmented manifest format (such as an HLS/DASH stream), yt-dlp passes insufficiently sanitized input to aria2c that allows an attacker to perform an arbitrary file write. On Windows platforms, this can lead to immediate arbitrary code execution. On non-Windows platforms, this can lead to arbitrary code execution upon the next invocation of yt-dlp. This vulnerability is fixed in 2026.06.09.
