{"id":"CVE-2025-8406","summary":"Path Traversal in zenml-io/zenml","details":"ZenML version 0.83.1 is affected by a path traversal vulnerability in the `PathMaterializer` class. The `load` function uses `is_path_within_directory` to validate files during `data.tar.gz` extraction, which fails to effectively detect symbolic and hard links. This vulnerability can lead to arbitrary file writes, potentially resulting in arbitrary command execution if critical files are overwritten.","aliases":["GHSA-q92x-2x5g-h365","PYSEC-2026-2071"],"modified":"2026-08-12T03:51:13.044988642Z","published":"2025-10-05T09:00:36.838Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8406.json","cna_assigner":"@huntr_ai"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/a0880d64-9928-45bf-9663-2cd81582d9e7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8406.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-8406"},{"type":"FIX","url":"https://github.com/zenml-io/zenml/commit/5d22a48d7bf6c7f10b748577c2be79cc7969d398"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zenml-io/zenml","events":[{"introduced":"e941c5eb6ba8899061e2849a4db66cfcb6c322a4"},{"fixed":"d6264356408ead438626b0e2e75386f992234eaf"},{"fixed":"5d22a48d7bf6c7f10b748577c2be79cc7969d398"}],"database_specific":{"cpe":"cpe:2.3:a:zenml:zenml:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.83.1"},{"fixed":"0.84.2"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["0.84.1","0.84.0","0.83.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-8406.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H"}]}
