CVE-2026-107388: 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 ID3v2 parser trusts the syncsafe tag-size field and allocates the complete tag body before checking whether the input contains the declared bytes. A truncated file containing only an ID3v2 header can request an allocation approaching 268 MiB; the allocation succeeds, the subsequent read reaches end of stream, the EndOfStreamError is caught internally, and the caller receives a normal metadata object. This issue is fixed in version 11.16.0.

Affected products

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