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.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21163-1 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)

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, 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
