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.

The remote Fedora 46 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-139d3aad5f advisory.

The detected version of the yt-dlp Python package is prior to 2026.6.9. It is, therefore, affected by multiple vulnerabilities:

  - 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.
    (CVE-2026-50023)

  - 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. (CVE-2026-50574)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2026-50023)
