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.","state":0,"publishedAt":"2026-10-08T19:05:23.816+00:00","modifiedAt":"2026-10-09T18:32:42.251+00:00","affected":[{"ecosystem":"Vendor product","name":"music-metadata","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Borewit\",\n                    \"product\": \"music-metadata\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 11.16.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","https://github.com/Borewit/music-metadata/pull/2735","https://github.com/Borewit/music-metadata/commit/163f013364ac9fc8dd0c3987433cd065a615af58","https://github.com/Borewit/music-metadata/commit/2d14dc1f7391a94235948a0b823155538f69b3df","https://github.com/Borewit/music-metadata/releases/tag/v11.16.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107389","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107389","identifiers":["CVE-2026-107389"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
