CVE-2026-107390
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.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- Base score: 7.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.13%
- Percentile among all scored CVEs: 2
- Score date: 10/14/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
