{"id":"CVE-2026-107390","aliases":["GHSA-qc8q-pw95-mq6c"],"url":"https://o3.security/vulnerability/CVE-2026-107390","summary":"music-metadata: MP4 parser allows memory exhaustion via oversized extended atom length","details":"music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the MP4 parser accepts an attacker-controlled 64-bit extended atom size, converts it to a JavaScript Number, and uses the resulting payload length for atom-specific readToken calls before proving that the atom fits within its parent or the available input. A tiny MP4-family file can route an oversized length into payload parsing for atoms including mvhd, stsd, stsz, and date, causing a large allocation attempt or process failure before end-of-input validation. Applications that parse untrusted MP4-family media can therefore be denied service. This issue is fixed in version 11.16.0.","published":"2026-10-08T19:09:08.729Z","modified":"2026-10-11T02:30:21.020668859Z","cvss":{"score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/Borewit/music-metadata/commit/0f19ad66d71889b1c5f3ba84d4824f079ac4c005","label":"Borewit/music-metadata@0f19ad6"},"references":[{"type":"WEB","url":"https://github.com/Borewit/music-metadata/releases/tag/v11.16.0"},{"type":"ADVISORY","url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-qc8q-pw95-mq6c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107390.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107390"},{"type":"FIX","url":"https://github.com/Borewit/music-metadata/commit/0f19ad66d71889b1c5f3ba84d4824f079ac4c005"},{"type":"FIX","url":"https://github.com/Borewit/music-metadata/pull/2746"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-11T02:30:21.020668859Z"}}
