{"id":"DEBIAN-CVE-2026-44353","details":"Streamlink is a CLI utility which pipes video streams from various services into a video player. Prior to 8.4.0, Streamlink's HLS and DASH parsers do not validate the URI scheme of segment entries and other resources. A remote .m3u8 HLS playlist or .mpd DASH manifest can list file:///path/to/file as a segment, and streamlink will read that local file and write its contents to the output stream. This vulnerability is fixed in 8.4.0.","modified":"2026-09-14T17:03:35.965819496Z","published":"2026-05-27T17:16:38.927Z","upstream":["CVE-2026-44353"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-44353"}],"affected":[{"package":{"name":"streamlink","ecosystem":"Debian:12","purl":"pkg:deb/debian/streamlink?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.1-1","5.5.1-1~exp1","6.0.1-1","6.1.0-1","6.10.0-1","6.10.0-1~bpo12+1","6.11.0-1","6.11.0-2","6.11.0-2~bpo12+1","6.2.0-1","6.2.0-1~bpo12+1","6.2.1-1","6.2.1-1~bpo12+1","6.3.0-1","6.3.1-1","6.3.1-1~bpo12+1","6.3.1-2","6.4.2-1","6.4.2-1~bpo12+1","6.5.0-1","6.5.0-1~bpo12+1","6.5.1-1","6.5.1-1~bpo12+1","6.6.1-1","6.6.2-1","6.6.2-1~bpo12+1","6.7.1-1","6.7.2-1","6.7.2-1~bpo12+1","6.7.3-1","6.7.3-1~bpo12+1","6.7.4-1","6.7.4-1~bpo12+1","6.8.1-1","6.8.2-1","6.8.3-1","6.8.3-1~bpo12+1","6.9.0-1","6.9.0-1~bpo12+1","7.0.0-1","7.0.0-1~bpo12+1","7.1.1-1","7.1.1-1~bpo12+1","7.1.2-1","7.1.2-1~bpo12+1","7.1.3-1","7.1.3-1~bpo12+1","7.2.0-1","7.3.0-1","7.3.0-2","7.3.0-2~bpo12+1","7.5.0-1","7.6.0-1","7.6.0-1~bpo13+1","7.6.0-2","8.0.0-1","8.0.0-1~bpo13+1","8.1.0-1","8.1.0-1~bpo13+1","8.1.2-1","8.2.0-1","8.2.0-1~bpo13+1","8.2.1-1","8.3.0-1","8.3.0-1~bpo13+1","8.4.0-1","8.4.0-2","8.4.0-2~bpo13+1","8.5.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44353.json"}},{"package":{"name":"streamlink","ecosystem":"Debian:13","purl":"pkg:deb/debian/streamlink?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.3.0-2","7.5.0-1","7.6.0-1","7.6.0-1~bpo13+1","7.6.0-2","8.0.0-1","8.0.0-1~bpo13+1","8.1.0-1","8.1.0-1~bpo13+1","8.1.2-1","8.2.0-1","8.2.0-1~bpo13+1","8.2.1-1","8.3.0-1","8.3.0-1~bpo13+1","8.4.0-1","8.4.0-2","8.4.0-2~bpo13+1","8.5.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44353.json"}},{"package":{"name":"streamlink","ecosystem":"Debian:14","purl":"pkg:deb/debian/streamlink?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.0-1"}]}],"versions":["7.3.0-2","7.5.0-1","7.6.0-1","7.6.0-1~bpo13+1","7.6.0-2","8.0.0-1","8.0.0-1~bpo13+1","8.1.0-1","8.1.0-1~bpo13+1","8.1.2-1","8.2.0-1","8.2.0-1~bpo13+1","8.2.1-1","8.3.0-1","8.3.0-1~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44353.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
