Summary

CVE-2026-35167 is a high-severity Path Traversal (CWE-22) vulnerability in Linuxfoundation Kedro. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as Data Processing Libraries; in the Data-Related Vulnerabilities risk domain.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-35167 is a path traversal vulnerability (CWE-22) in Kedro, a toolbox for production-ready data science, affecting versions prior to 1.3.0. The flaw occurs in the _get_versioned_path() method within kedro/io/core.py, which constructs filesystem paths by directly interpolating user-supplied version strings without sanitization. As a result, traversal sequences such as ../ are preserved, allowing escape from the intended versioned dataset directory. The vulnerability was published on 2026-04-06 and carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).

An attacker who can influence the version string can exploit this issue through multiple entry points, including catalog.load(..., version=...), DataCatalog.from_config(..., load_versions=...), and the CLI via kedro run --load-versions=dataset:../../../secrets. Exploitation requires low privileges (PR:L) and is network-accessible with low complexity (AC:L), enabling the loading of files from outside the intended version directory. Potential impacts include unauthorized file reads, data poisoning, or cross-tenant data access in shared environments.

The vulnerability is addressed in Kedro 1.3.0. Additional details on the fix and mitigation are available in the GitHub security advisory at https://github.com/kedro-org/kedro/security/advisories/GHSA-6326-w46w-ppjw and the related pull request at https://github.com/kedro-org/kedro/pull/5442.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
