CVE-2026-55404 (opens in a new tab)How to fix?
There is no fixed version for Debian:13 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:13 relevant fixed versions and status.
yt-dlp and youtube-dl are command-line audio/video downloaders. Prior to 2026.7.4, the --write-link, --write-url-link, and --write-desktop-link options can write .url or .desktop shortcut files using attacker-controlled webpage_url or filename metadata without sufficient validation or escaping, allowing malicious file:// URI injection on Windows or newline-based desktop entry key injection on Linux that can execute commands if the generated shortcut is opened. This issue is fixed in version 2026.7.4.
