# CVE-2026-35167

> 7.1 HIGH · 🧪 PoC

## Beschreibung

Kedro is a toolbox for production-ready data science. Prior to 1.3.0, the _get_versioned_path() method in kedro/io/core.py constructs filesystem paths by directly interpolating user-supplied version strings without sanitization. Because version strings are used as path components, traversal sequences such as ../ are preserved and can escape the intended versioned dataset directory.
This is reachable through multiple entry points: catalog.load(..., version=...), DataCatalog.from_config(..., load_versions=...), and the CLI via kedro run --load-versions=dataset:../../../secrets. An attacker who can influence the version string can force Kedro to load files from outside the intended version directory, enabling unauthorized file reads, data poisoning, or cross-tenant data access in shared environments. This vulnerability is fixed in 1.3.0.
