{"id":"PYSEC-2026-180","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.","aliases":["CVE-2026-44353","GHSA-hgqw-6m45-hw5f"],"modified":"2026-06-02T12:15:10.871845747Z","published":"2026-05-27T17:16:38.927Z","references":[{"type":"EVIDENCE","url":"https://github.com/streamlink/streamlink/security/advisories/GHSA-hgqw-6m45-hw5f"}],"affected":[{"package":{"name":"streamlink","ecosystem":"PyPI","purl":"pkg:pypi/streamlink"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.0"}]}],"versions":["0.0.1","0.0.2","0.1.0","0.10.0","0.11.0","0.12.0","0.12.1","0.13.0","0.14.0","0.14.2","0.2.0","0.3.0","0.3.1","0.3.2","0.4.0","0.5.0","0.6.0","0.7.0","0.8.1","0.9.0","1.0.0","1.1.0","1.1.1","1.2.0","1.3.0","1.3.1","1.4.0","1.4.1","1.5.0","1.6.0","1.7.0","2.0.0","2.1.0","2.1.1","2.1.2","2.2.0","2.3.0","2.4.0","3.0.0","3.0.1","3.0.2","3.0.3","3.1.0","3.1.1","3.2.0","4.0.0","4.0.1","4.1.0","4.2.0","4.3.0","5.0.0","5.0.1","5.1.0","5.1.1","5.1.2","5.2.1","5.3.0","5.3.1","5.4.0","5.5.0","5.5.1","6.0.0","6.0.1","6.1.0","6.10.0","6.11.0","6.2.0","6.2.1","6.3.0","6.3.1","6.4.0","6.4.1","6.4.2","6.5.0","6.5.1","6.6.0","6.6.1","6.6.2","6.7.0","6.7.1","6.7.2","6.7.3","6.7.4","6.8.0","6.8.1","6.8.2","6.8.3","6.9.0","7.0.0","7.1.0","7.1.1","7.1.2","7.1.3","7.2.0","7.3.0","7.4.0","7.5.0","7.6.0","8.0.0","8.1.0","8.1.1","8.1.2","8.2.0","8.2.1","8.3.0"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/streamlink/PYSEC-2026-180.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
