CVE-2026-35167Network attack vector

Unauthorized file reads via unsanitized version paths

Published Apr 6, 2026 · Updated Apr 6, 2026

Path traversal in Kedro before 1.3.0 allows remote authenticated users to read files outside the intended dataset directory. The _get_versioned_path() method in kedro/io/core.py inserts an unvalidated version string directly into a filesystem path, preserving ../ traversal segments. Reachability requires control of a version argument through catalog.load, DataCatalog configuration, or the --load-versions CLI option; successful use exposes files accessible to the Kedro process and can select unintended data for processing.
