{"id":"CVE-2026-44353","aliases":["GHSA-hgqw-6m45-hw5f","PYSEC-2026-180"],"url":"https://o3.security/vulnerability/CVE-2026-44353","summary":"Streamlink: Arbitrary local file read via file:// URI in HLS and DASH","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.","published":"2026-05-27T15:10:23.537Z","modified":"2026-07-15T01:49:11.308447347Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"streamlink","fixedVersion":"8.4.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44353.json"},{"type":"ADVISORY","url":"https://github.com/streamlink/streamlink/security/advisories/GHSA-hgqw-6m45-hw5f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44353"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:11.308447347Z"}}
