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:14 relevant fixed versions and status.

yt-dlp is a command-line audio/video downloader. Prior to 2026.06.09, a vulnerability exists in yt-dlp that allows a remote attacker to write arbitrary OS-shortcut files (such as .desktop, .url, .webloc) to the user's filesystem, bypassing the remediation for CVE-2024-38519. The allowlist explicitly included the unsafe extensions .desktop, .url, and .webloc so that the functionality of the --write-link option (and its variants) could be preserved. These allowlist inclusions can be exploited by an attacker to write malicious OS-shortcut files in the context of a media or subtitles download. This vulnerability is fixed in 2026.06.09.
