CVE-2026-107390: Borewit Music-Metadata

Medium severity, CVSS 6.2. EPSS: 0.1% chance of exploitation in the next 30 days.

music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the MP4 parser accepts an attacker-controlled 64-bit extended atom size, converts it to a JavaScript Number, and uses the resulting payload length for atom-specific readToken calls before proving that the atom fits within its parent or the available input. A tiny MP4-family file can route an oversized length into payload parsing for atoms including mvhd, stsd, stsz, and date, causing a large allocation attempt or process failure before end-of-input validation. Applications that parse untrusted MP4-family media can therefore be denied service. This issue is fixed in version 11.16.0.

Affected products

• Borewit Music-Metadata: before 11.16.0 (fixed in 11.16.0)
