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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"Borewit","product":"music-metadata","versions":[{"version":"< 11.16.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":6.2,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.5,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-09T18:32:35.247883Z","id":"CVE-2026-107389","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-789"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:borewit:music-metadata:*:*:*:*:*:*:*:*","versionEndExcluding":"11.16.0","matchCriteriaId":"02A24B53-9B9C-4DB5-BB83-1586AF41148A"}]}]}],"references":[{"url":"https://github.com/Borewit/music-metadata/commit/163f013364ac9fc8dd0c3987433cd065a615af58","source":"security-advisories@github.com","tags":["Exploit","Patch"]},{"url":"https://github.com/Borewit/music-metadata/commit/2d14dc1f7391a94235948a0b823155538f69b3df","source":"security-advisories@github.com","tags":["Exploit","Patch"]},{"url":"https://github.com/Borewit/music-metadata/pull/2735","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/Borewit/music-metadata/releases/tag/v11.16.0","source":"security-advisories@github.com","tags":["Patch","Release Notes"]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","source":"security-advisories@github.com","tags":["Exploit","Patch","Vendor Advisory"]},{"url":"https://github.com/Borewit/music-metadata/security/advisories/GHSA-5gfj-9q3v-qfp3","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Patch","Vendor Advisory"]}]}
