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.

EchelonGraph scoreLOW confidence
This high-severity CVE scores 7.5 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).
