{"id":"DEBIAN-CVE-2026-50574","details":"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.","modified":"2026-08-27T23:06:26.151738815Z","published":"2026-06-23T17:17:03.340Z","upstream":["CVE-2026-50574"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-50574"}],"affected":[{"package":{"name":"yt-dlp","ecosystem":"Debian:12","purl":"pkg:deb/debian/yt-dlp?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2023.03.04-1","2023.06.21-1","2023.06.22-1","2023.06.22-1~bpo12+1","2023.07.06-1","2023.07.06-1~bpo12+1","2023.09.24-1","2023.09.24-2","2023.09.24-2~bpo12+1","2023.10.07-1","2023.10.07-1~bpo12+1","2023.10.13-1","2023.10.13-1~bpo11+1","2023.10.13-1~bpo12+1","2023.11.16-1","2023.11.16-1~bpo11+1","2023.11.16-1~bpo12+1","2023.12.30-1","2024.03.10-1","2024.03.10-1~bpo12+1","2024.04.09-1","2024.04.09-1~bpo12+1","2024.05.26-1","2024.05.26-1~bpo12+1","2024.05.27-1","2024.05.27-1~bpo12+1","2024.07.01-1","2024.07.02-1","2024.07.02-1~bpo12+1","2024.07.07-1","2024.07.09-1","2024.07.09-1~bpo12+1","2024.07.16-1","2024.07.16-1~bpo12+1","2024.07.25-1","2024.07.25-1~bpo12+1","2024.08.01-1","2024.08.01-1~bpo12+1","2024.08.06-1","2024.08.06-1~bpo12+1","2024.09.27-1","2024.09.27-1~bpo12+1","2024.10.07-1","2024.10.07-1~bpo12+1","2024.10.22-1","2024.10.22-1~bpo12+1","2024.11.04-1","2024.11.18-1","2024.11.18-1~bpo12+1","2024.12.03-1","2024.12.03-1~bpo12+1","2024.12.06-1","2024.12.06-1~bpo12+1","2024.12.13-1","2024.12.13-1~bpo12+1","2024.12.23-1","2024.12.23-1~bpo12+1","2025.01.12-1","2025.01.12-1~bpo12+1","2025.01.15-1","2025.01.15-1~bpo12+1","2025.01.26-1","2025.01.26-1~bpo12+1","2025.02.19-1","2025.02.19-1~bpo12+1","2025.03.21-1","2025.03.21-1~bpo12+1","2025.03.25-1","2025.03.26-1","2025.03.26-1~bpo12+1","2025.03.27-1","2025.03.27-1~bpo12+1","2025.03.31-1","2025.03.31-1~bpo12+1","2025.04.30-1","2025.04.30-1~bpo12+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","2025.08.11-1~bpo13+1","2025.08.20-1","2025.08.22-1","2025.08.27-1","2025.08.27-1~bpo13+1","2025.09.05-1","2025.09.05-1~bpo13+1","2025.09.23-1","2025.09.26-1","2025.09.26-1~bpo13+1","2025.10.14-1","2025.10.14-1~bpo13+1","2025.10.22-1","2025.10.22-1~bpo13+1","2025.11.12-1","2025.11.12-1~bpo13+1","2025.12.08-1","2025.12.08-1~bpo13+1","2026.01.31-1","2026.01.31-1~bpo13+1","2026.02.21-1","2026.02.21-1~bpo13+1","2026.03.03-1","2026.03.03-1~bpo13+1","2026.03.13-1","2026.03.13-1~bpo13+1","2026.03.17-1","2026.03.17-1~bpo13+1","2026.06.09-1","2026.06.09-1~bpo13+1","2026.07.04-1","2026.07.04-1~bpo13+1","2026.08.19-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50574.json"}},{"package":{"name":"yt-dlp","ecosystem":"Debian:13","purl":"pkg:deb/debian/yt-dlp?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["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","2025.08.11-1~bpo13+1","2025.08.20-1","2025.08.22-1","2025.08.27-1","2025.08.27-1~bpo13+1","2025.09.05-1","2025.09.05-1~bpo13+1","2025.09.23-1","2025.09.26-1","2025.09.26-1~bpo13+1","2025.10.14-1","2025.10.14-1~bpo13+1","2025.10.22-1","2025.10.22-1~bpo13+1","2025.11.12-1","2025.11.12-1~bpo13+1","2025.12.08-1","2025.12.08-1~bpo13+1","2026.01.31-1","2026.01.31-1~bpo13+1","2026.02.21-1","2026.02.21-1~bpo13+1","2026.03.03-1","2026.03.03-1~bpo13+1","2026.03.13-1","2026.03.13-1~bpo13+1","2026.03.17-1","2026.03.17-1~bpo13+1","2026.06.09-1","2026.06.09-1~bpo13+1","2026.07.04-1","2026.07.04-1~bpo13+1","2026.08.19-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50574.json"}},{"package":{"name":"yt-dlp","ecosystem":"Debian:14","purl":"pkg:deb/debian/yt-dlp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2026.06.09-1"}]}],"versions":["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","2025.08.11-1~bpo13+1","2025.08.20-1","2025.08.22-1","2025.08.27-1","2025.08.27-1~bpo13+1","2025.09.05-1","2025.09.05-1~bpo13+1","2025.09.23-1","2025.09.26-1","2025.09.26-1~bpo13+1","2025.10.14-1","2025.10.14-1~bpo13+1","2025.10.22-1","2025.10.22-1~bpo13+1","2025.11.12-1","2025.11.12-1~bpo13+1","2025.12.08-1","2025.12.08-1~bpo13+1","2026.01.31-1","2026.01.31-1~bpo13+1","2026.02.21-1","2026.02.21-1~bpo13+1","2026.03.03-1","2026.03.03-1~bpo13+1","2026.03.13-1","2026.03.13-1~bpo13+1","2026.03.17-1","2026.03.17-1~bpo13+1","2026.06.09-1~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50574.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
