CVE-2026-3840

Summary

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.
