CVE-2026-107389
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.
