CVE-2026-46695

Boxlite is a sandbox service that allows users to create lightweight virtual machines (Boxes) and launch OCI containers within them to run untrusted code. Prior to version 0.9.0, Boxlite does not restrict the kernel capabilities available inside the container, malicious code can remount the directory in rw mode, thereby gaining write access to that directory. This allows malicious code to perform arbitrary write operations on directories that should be read-only. This issue has been patched in version 0.9.0.

Summary		(es) Boxlite es un servicio de sandbox que permite a los usuarios crear máquinas virtuales ligeras (Boxes) y lanzar contenedores OCI dentro de ellas para ejecutar código no confiable. Antes de la versión 0.9.0, Boxlite no restringe las capacidades del kernel disponibles dentro del contenedor, el código malicioso puede remontar el directorio en modo rw, obteniendo así acceso de escritura a ese directorio. Esto permite al código malicioso realizar operaciones de escritura arbitrarias en directorios que deberían ser de solo lectura. Este problema ha sido parcheado en la versión 0.9.0.
