CVE-2026-107388

Estado: ModificadaMedia (5.5)—

music-metadata es un analizador de metadatos para archivos multimedia de audio y vídeo. En versiones anteriores a la 11.16.0, el analizador ID3v2 confía en el campo syncsafe de tamaño de etiqueta y asigna el cuerpo completo de la etiqueta antes de comprobar si la entrada contiene los bytes declarados. Un archivo truncado que contenga solo una cabecera ID3v2 puede solicitar una asignación de cerca de 268 MiB; la asignación tiene éxito, la lectura posterior llega al final del flujo, el EndOfStreamError se captura internamente y el llamante recibe un objeto de metadatos normal. Este problema está corregido en la versión 11.16.0.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso local (AV:L) sin interacción de usuario permite asignación excesiva de memoria (CWE-789) causando DoS por agotamiento de recursos; explotación de aplicación para escalar o denegar servicio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

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."
