What is CVE-2026-107392?
CVE-2026-107392 is a medium-severity denial of service vulnerability in Borewit music-metadata, published on 8 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
music-metadata is a metadata parser for audio and video media files. Prior to 11.15.0, the DSF parser handles an unrecognized chunk by calling tokenizer.ignore without awaiting the returned promise and without first rejecting a chunk size smaller than the 12-byte chunk header. A crafted DSF input can produce a negative ignore length; with strtok3 10.3.5 or later, the resulting RangeError is detached from the parseBuffer promise and becomes an unhandled rejection under Node.js default behavior. The parse call can appear to resolve before the process crashes, bypassing per-parse try/catch handling. The demonstrated impact is availability loss only and requires the DSF parsing path. This issue is fixed in version 11.15.0.
