CVE-2026-107390
MEDIUMDescription
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.
