{"cve":"CVE-2026-8597","nvd":{"published":"2026-05-14T20:17:21.340","modified":"2026-10-20T19:19:23.343","status":"Awaiting Analysis","description":"Missing integrity verification in the Triton inference handler in Amazon SageMaker Python SDK v2 before v2.257.2 and v3 before v3.8.0 might allow a remote authenticated actor to achieve code execution in inference containers via replacement of model artifacts in S3 with a specially crafted pickle payload that is deserialized without verification. This issue requires a remote authenticated actor with S3 write access to the model artifact path.\n\n\n\nTo remediate this issue, we recommend upgrading to Amazon SageMaker Python SDK v2.257.2 or v3.8.0 and rebuild any Triton models previously created with ModelBuilder using the updated SDK.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":6.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2},"cwes":["CWE-354"],"references":["https://aws.amazon.com/security/security-bulletins/2026-031-aws/","https://github.com/aws/sagemaker-python-sdk/releases/tag/v2.257.2","https://github.com/aws/sagemaker-python-sdk/releases/tag/v3.8.0","https://github.com/aws/sagemaker-python-sdk/security/advisories/GHSA-rq6v-x3j8-7qgf"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-8597","score":0.00507,"percentile":0.42997,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rq6v-x3j8-7qgf","url":"https://osv.dev/vulnerability/GHSA-rq6v-x3j8-7qgf","summary":"Amazon SageMaker Python SDK is missing integrity verification in its Triton inference handler","modified":"2026-07-13T16:42:37.300995535Z","packages":[{"ecosystem":"PyPI","name":"sagemaker","purl":"pkg:pypi/sagemaker","ranges":[">=2.199.0 <2.257.2"],"fixed":["2.257.2"]},{"ecosystem":"PyPI","name":"sagemaker","purl":"pkg:pypi/sagemaker","ranges":[">=3.0.0 <3.8.0"],"fixed":["3.8.0"]}]},{"id":"PYSEC-2026-3060","url":"https://osv.dev/vulnerability/PYSEC-2026-3060","summary":"Amazon SageMaker Python SDK is missing integrity verification in its Triton inference handler","modified":"2026-07-13T16:31:47.295371996Z","packages":[{"ecosystem":"PyPI","name":"sagemaker","purl":"pkg:pypi/sagemaker","ranges":[">=2.199.0 <2.257.2",">=3.0.0 <3.8.0"],"fixed":["2.257.2","3.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
