{"cve":"CVE-2026-107389","nvd":{"published":"2026-10-08T20:17:33.190","modified":"2026-10-21T15:34:25.303","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-789"],"references":["https://github.com/Borewit/music-metadata/commit/163f013364ac9fc8dd0c3987433cd065a615af58","https://github.com/Borewit/music-metadata/commit/2d14dc1f7391a94235948a0b823155538f69b3df","https://github.com/Borewit/music-metadata/pull/2735","https://github.com/Borewit/music-metadata/releases/tag/v11.16.0","https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3"],"products":["borewit:music-metadata"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-107389","score":0.00214,"percentile":0.11675,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5gfj-9q3v-qfp3","url":"https://osv.dev/vulnerability/GHSA-5gfj-9q3v-qfp3","summary":"music-metadata: EBML parser trusts element lengths, allowing memory exhaustion or process abort","modified":"2026-10-08T20:00:05.878232877Z","packages":[{"ecosystem":"npm","name":"music-metadata","purl":"pkg:npm/music-metadata","ranges":["<11.16.0"],"fixed":["11.16.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
