{"id":"CVE-2026-35167","summary":"Kedro has a path traversal in versioned dataset loading via unsanitized version string","details":"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.\nThis 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.","aliases":["GHSA-6326-w46w-ppjw","PYSEC-2026-71"],"modified":"2026-07-15T01:48:58.525365609Z","published":"2026-04-06T17:43:21.922Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35167.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35167.json"},{"type":"ADVISORY","url":"https://github.com/kedro-org/kedro/security/advisories/GHSA-6326-w46w-ppjw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35167"},{"type":"FIX","url":"https://github.com/kedro-org/kedro/pull/5442"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kedro-org/kedro","events":[{"introduced":"0"},{"fixed":"d1af1822687a438a0f3fba8913a919d06e02c298"}],"database_specific":{"cpe":"cpe:2.3:a:linuxfoundation:kedro:*:*:*:*:*:python:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.3.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["1.2.0","1.1.1","1.1.0","0.19.14","1.0.0","1.0.0rc3","1.0.0rc2","1.0.0rc1","0.19.13","0.19.12","0.19.11","0.19.10","0.19.9","0.19.8","0.19.7","0.19.6","0.19.0","0.19.1","0.19.2","0.19.3","0.19.4","0.19.5","0.18.14","0.18.13","0.18.12","0.18.11","0.18.10","0.18.9","0.18.8","0.18.7","0.18.6","0.18.5","0.18.4","0.18.3","0.18.2","0.18.1","0.18.0","0.17.7","0.17.6","0.17.5","0.17.4","0.17.3","0.17.2","0.17.1","0.17.0","0.16.6","0.16.5","0.16.4","0.16.3","0.16.2","0.16.1","0.16.0","0.15.9","0.15.8","0.15.7","0.15.6","0.15.5","0.15.4","0.15.3","0.15.2","0.15.1","0.15.0","0.14.3","0.14.2","0.14.1","0.14.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35167.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}
