NewCVE-2026-107389 (opens in a new tab)How to fix?
Upgrade music-metadata to version 11.16.0 or higher.
Overview
music-metadata is a Music metadata parser for Node.js, supporting virtual any audio and tag format.
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the EBML element parser in EbmlIterator.ts, where an attacker-controlled element length field is not validated before buffer or string allocation. By supplying an EBML input with an oversized declared leaf element length, an attacker can trigger allocation of hundreds of megabytes or gigabytes of memory, crashing the process.
