yt-dlp: yt-dlp and youtube-dl are command-line audio/video downloaders
CVE-2026-55404 is fixed in yt-dlp on 1 platform, first by DEBIAN-CVE-2026-55404, released July 10, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
