CVE-2026-62867

Incus is a system container and virtual machine manager. Prior to version 7.3.0, improper validation of user-provided `block.create_options` in storage volume configuration leads to argument injection in the constructed filesystem creation command line. This allows a project-scoped user to inject arbitrary arguments into the binary executed as root. Version 7.3.0 patches the issue.

Summary		(es) Incus es un gestor de contenedores de sistema y máquinas virtuales. Antes de la versión 7.3.0, una validación incorrecta de los 'block.create_options' proporcionados por el usuario en la configuración del volumen de almacenamiento conduce a la inyección de argumentos en la línea de comandos de creación del sistema de archivos construida. Esto permite a un usuario con ámbito de proyecto inyectar argumentos arbitrarios en el binario ejecutado como root. La versión 7.3.0 corrige el problema.
