{"id":"CVE-2026-107389","published":"2026-10-08T20:17:33.190","lastModified":"2026-10-09T19:16:41.583","description":"music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the Matroska and WebM EBML parser decodes an attacker-controlled VINT element length and uses it for string-token or Uint8Array allocation before confirming that the leaf fits within its parent or available input. Crafted WebM, MKV, or MKA inputs can cause disproportionate allocations, out-of-memory denial of service, or, for a demonstrated parseFile path on Node.js 26.7.0, an uncatchable V8 fatal abort. The exact failure mode depends on the tokenizer, parser API, and runtime, but the affected leaf-length validation flaw is shared and has availability impact only. This issue is fixed in version 11.16.0.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-789"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Borewit/music-metadata/commit/163f013364ac9fc8dd0c3987433cd065a615af58","tags":[]},{"url":"https://github.com/Borewit/music-metadata/commit/2d14dc1f7391a94235948a0b823155538f69b3df","tags":[]},{"url":"https://github.com/Borewit/music-metadata/pull/2735","tags":[]},{"url":"https://github.com/Borewit/music-metadata/releases/tag/v11.16.0","tags":[]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","tags":[]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","tags":[]}],"exploitRefs":[{"url":"https://github.com/Borewit/music-metadata/commit/163f013364ac9fc8dd0c3987433cd065a615af58","tags":[]},{"url":"https://github.com/Borewit/music-metadata/commit/2d14dc1f7391a94235948a0b823155538f69b3df","tags":[]},{"url":"https://github.com/Borewit/music-metadata/pull/2735","tags":[]},{"url":"https://github.com/Borewit/music-metadata/releases/tag/v11.16.0","tags":[]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","tags":[]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","tags":[]}],"hasPoc":true,"ai":null}
