This medium-severity CVE scores 6.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

music-metadata is a metadata parser for audio and video media files. In the public development revision introduced after 11.14.0, a development-branch regression in the MP4 stsd sample-description parser allows an attacker-controlled sample-entry size of zero to prevent the StsdAtom.get cursor from advancing while an attacker-controlled entry_count keeps the synchronous loop running. A crafted MP4-family input can block the Node.js event loop and grow the sample-description table until the process is terminated or exhausts memory. The vulnerable change was present on the public master branch but was not included in music-metadata 11.14.0 or any earlier npm release, and version 11.16.0 contains the fix. This issue is fixed in version 11.16.0.
