CVE-2025-67818

An issue was discovered in Weaviate OSS before 1.33.4. An attacker with access to insert data into the database can craft an entry name with an absolute path (e.g., /etc/...) or use parent directory traversal (../../..) to escape the restore root when a backup is restored, potentially creating or overwriting files in arbitrary locations within the application's privilege scope.

Summary		(es) Se descubrió un problema en Weaviate OSS anterior a la versión 1.33.4. Un atacante con acceso para insertar datos en la base de datos puede crear un nombre de entrada con una ruta absoluta (por ejemplo, /etc/...) o usar el salto de directorio padre (.. / ../..) para escapar de la raíz de restauración cuando se restaura una copia de seguridad, lo que podría crear o sobrescribir archivos en ubicaciones arbitrarias dentro del alcance de privilegios de la aplicación.
