No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-112408/ (Markdown: https://insights.sbomify.com/CVE-2026-112408/index.md)","id":"CVE-2026-112408","markdown":"https://insights.sbomify.com/CVE-2026-112408/index.md","name":"CVE-2026-112408","record":{"aliases":["GHSA-5rx8-8fr2-f855"],"analysis":null,"analysis_generated_by":null,"assigner":"AMZN","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"Missing verification of source of a communication channel in the default_bucket() function in Amazon SageMaker Python SDK V3 before 3.10.0 and V2 before 2.257.3 might allow remote actors to achieve code execution in the target SageMaker execution environment and obtain IAM credentials via pre-creation of a predictably named S3 bucket that the SDK uses without ownership validation.\n\nTo remediate this issue, users should upgrade to Amazon SageMaker Python SDK 3.10.0 (V3) or 2.257.3 (V2).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Missing bucket ownership verification in Amazon SageMaker Python SDK default_bucket()","id":"CVE-2026-112408","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"A double free issue was addressed with improved memory management.","id":"CVE-2026-112410"},"packages":[],"prev":{"headline":"Incorrect privilege assignment in AWS CICD-toolchain-for-serverless-applications","id":"CVE-2026-112407"},"products":["Amazon SageMaker Python SDK"],"published":"2026-10-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["AWS"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-112408/"}
