{"id":"CVE-2026-68772","summary":"ZenML 0.94.6 Remote Code Execution via CloudpickleMaterializer","details":"ZenML 0.94.6 contains a remote code execution vulnerability in the CloudpickleMaterializer component that allows attackers with write access to a shared artifact store to execute arbitrary code by planting a malicious pickle file. Attackers can replace a stored artifact.pkl file with a crafted cloudpickle payload containing a malicious __reduce__ method, which executes arbitrary system commands when any user or pipeline materializes the artifact through the unsanitized cloudpickle.load() call in cloudpickle_materializer.py.","modified":"2026-08-15T04:07:00.667902994Z","published":"2026-08-07T16:27:41.783Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68772.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-502"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68772.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68772"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zenml-remote-code-execution-via-cloudpicklematerializer"},{"type":"REPORT","url":"https://github.com/zenml-io/zenml/pull/5103"},{"type":"FIX","url":"https://github.com/zenml-io/zenml/commit/bbf8496d049a7e23800bc31b87b10b4fefbebe18"},{"type":"PACKAGE","url":"https://github.com/zenml-io/zenml"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zenml-io/zenml","events":[{"introduced":"0"},{"fixed":"bbf8496d049a7e23800bc31b87b10b4fefbebe18"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.94.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["0.96.2","0.96.1","0.96.0","0.95.1","0.95.0","0.94.5","0.94.4","0.94.3","0.94.2","0.94.1","0.94.0rc0","0.94.0","0.93.3","0.93.2","0.92.0","0.91.2","0.91.0","0.85.0","0.84.3","0.84.2","0.84.1","0.84.0","0.83.1","0.83.0","0.82.1","0.82.0","0.81.0","0.80.2","0.80.1","0.70.0","0.71.0","0.72.0","0.73.0","0.74.0","0.75.0","0.80.0","0.68.0","0.67.0","0.66.0","0.65.0","0.64.0","0.63.0","0.62.0","0.60.0","0.58.2","0.58.1","0.58.0","0.57.1","0.57.0","0.57.0rc2","0.57.0rc1","0.56.4","0.56.2","0.56.1","0.56.0","0.55.5","0.55.4","0.54.1","0.54.0","0.47.0","0.46.1","0.45.6","0.45.5","0.45.4","0.45.3","0.45.2","0.45.1","0.44.3","0.45.0","0.13.1","0.21.1","0.32.1","0.35.0","0.39.1","0.44.2","0.42.0","0.41.0","0.44.1","0.44.0","0.43.0","0.39.0","0.40.0","0.40.2","0.40.1","0.38.0","0.37.0","0.36.1","0.35.1","0.34.0","0.33.0","0.32.0","0.31.1","0.31.0","0.30.0","0.23.0","0.22.0","0.21.0","0.20.5","0.20.3","0.13.2","0.13.0","0.12.0","0.11.0","0.10.0","0.9.0","0.8.1","0.8.1rc0","0.7.1","0.7.0","0.6.3","0.6.2","0.5.7","0.5.6","0.5.5","0.5.4","0.5.3","0.5.2","0.5.1","0.5.0","0.5.0rc2","0.5.0rc1","0.3.9rc2","0.3.9rc1","0.3.8","0.3.7.1rc5","0.3.7.1rc4","0.3.7.1rc3","0.3.7.1rc2","0.3.7.1rc1","0.3.7.1rc0","0.3.7","0.3.7rc0","0.3.6.1","0.3.6","0.3.6rc0","0.3.5","0.3.5rc0","0.3.4","0.3.4rc0","0.3.3","0.3.3rc0","0.3.2","0.3.1","0.3.1rc0","0.3.0","0.2.0","0.2.0rc2","0.2.0rc1","0.1.3","0.1.3rc0","0.1.2","0.1.1","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68772.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
