CVE-2026-44692

Estado: AplazadaAlta (7.7)—

Sharp is a content management framework built for Laravel as a package. Prior to version 9.22.0, Sharp exposes a generic download endpoint that authorizes access only to the supplied Sharp entity instance, but then reads the target storage disk and path from request parameters. Because the requested storage object is not bound to the authorized entity instance, an authenticated Sharp user who can view one valid record may use that record as an authorization anchor to download unrelated disk-relative objects from configured Laravel Storage disks.

The confirmed impact is authenticated disclosure of unrelated objects from configured Laravel Storage disks. This issue does not imply arbitrary host filesystem access outside configured Laravel Storage disk roots. This issue has been patched in version 9.22.0.

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.

AV:N/PR:L permite T1210 (servicios remotos con privilegios). El atacante autenticado accede a objetos no autorizados del almacenamiento, logrando lectura de datos (T1005) y potencial exposición de credenciales/secretos almacenados (T1552).

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.

Antes de la versión 9.22.0, Sharp expone un endpoint de descarga genérico que autoriza el acceso solo a la instancia de entidad Sharp proporcionada, pero luego lee el disco de almacenamiento de destino y la ruta de los parámetros de la solicitud. Debido a que el objeto de almacenamiento solicitado no está vinculado a la instancia de entidad autorizada, un usuario autenticado de Sharp que puede ver un registro válido puede usar ese registro como un ancla de autorización para descargar objetos no relacionados relativos al disco de los discos de almacenamiento de Laravel configurados. El impacto confirmado es la divulgación autenticada de objetos no relacionados de los discos de almacenamiento de Laravel configurados. Este problema no implica acceso arbitrario al sistema de archivos del host fuera de las raíces de los discos de almacenamiento de Laravel configurados.
