{"id":"UBUNTU-CVE-2026-50023","details":"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.","modified":"2026-06-29T13:54:17.207156191Z","published":"2026-06-23T17:17:00Z","upstream":["CVE-2026-50023"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-50023"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-50023"}],"affected":[{"package":{"name":"yt-dlp","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/yt-dlp?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2021.12.01-1","2021.12.27-1","2022.01.21-1","2022.02.04-1","2022.03.08.1-1","2022.04.08-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2022.04.08-1","binary_name":"yt-dlp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50023.json"}},{"package":{"name":"yt-dlp","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/yt-dlp?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2023.07.06-1","2023.10.13-1ubuntu1","2023.11.16-1","2023.12.30-1ubuntu1","2024.03.10-1","2024.04.09-1"],"ecosystem_specific":{"binaries":[{"binary_name":"yt-dlp","binary_version":"2024.04.09-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50023.json"}},{"package":{"name":"yt-dlp","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/yt-dlp?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2025.03.27-1","2025.04.30-1","2025.05.22-1","2025.06.09-1","2025.06.25-1","2025.06.30-1","2025.07.21-1","2025.08.11-1","2025.08.20-1","2025.08.22-1","2025.08.27-1","2025.09.05-1","2025.09.23-1"],"ecosystem_specific":{"binaries":[{"binary_name":"yt-dlp","binary_version":"2025.09.23-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50023.json"}},{"package":{"name":"yt-dlp","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/yt-dlp?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2025.09.23-1","2025.10.22-1","2025.11.12-1","2025.12.08-1","2026.01.31-1","2026.03.17-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2026.03.17-1","binary_name":"yt-dlp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-50023.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
