CVE-2026-32256: Borewit Music-Metadata

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

music-metadata is a metadata parser for audio and video media files. Prior to version 11.12.3, music-metadata's ASF parser (`parseExtensionObject()` in `lib/asf/AsfParser.ts:112-158`) enters an infinite loop when a sub-object inside the ASF Header Extension Object has `objectSize = 0`. Version 11.12.3 fixes the issue.

Affected products

• Borewit Music-Metadata: before 11.12.3 (fixed in 11.12.3)
