CVE-2026-3840
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
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 directly interpolates user-supplied version strings into filesystem paths without sanitization, enabling access to files outside the intended dataset directory.
Risk Assessment
The risk associated with this vulnerability includes unauthorized file reads, data poisoning, and cross-project or cross-tenant data access, which can lead to serious consequences in automated environments.
Recommendation
It is recommended to update Kedro to the latest version to mitigate this vulnerability and to implement additional validation mechanisms for version strings in applications using Kedro.
Original NVD description (English source)
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.
