      "value": "A vulnerability in Kedro version 1.2.0 allows an attacker to exploit path traversal by providing a crafted version string. The `_get_versioned_path()` method in `kedro/io/core.py` directly interpolates user-supplied version strings into filesystem paths without sanitization. This enables an attacker to escape the intended versioned dataset directory and access files outside the expected path. The issue is also reachable through the CLI via the `--load-versions` parameter, as `_split_load_versions()` in `kedro/framework/cli/utils.py` does not validate the version string. This vulnerability can lead to unauthorized file reads, data poisoning, cross-project or cross-tenant data access, and broader downstream impacts in environments where Kedro is used with automation or orchestration layers."

El m\u00e9todo \u201c_get_versioned_path()\u201d en \u201ckedro/io/core.py\u201d interpola directamente las cadenas de versi\u00f3n proporcionadas por el usuario en las rutas del sistema de archivos sin saneamiento. Esto permite a un atacante escapar del directorio de conjunto de datos versionado previsto y acceder a archivos fuera de la ruta esperada. El problema tambi\u00e9n es accesible a trav\u00e9s de la CLI mediante el par\u00e1metro \u201c--load-versions\u201d, ya que \u201c_split_load_versions()\u201d en \u201ckedro/framework/cli/utils.py\u201d no valida la cadena de versi\u00f3n. Esta vulnerabilidad puede conducir a lecturas de archivos no autorizadas, envenenamiento de datos, acceso a datos entre proyectos o entre inquilinos, y a impactos descendentes m\u00e1s amplios en entornos donde Kedro se utiliza con capas de automatizaci\u00f3n u orquestaci\u00f3n."
