Attackers can supply a crafted bentofile.yaml or imported bento archive so that bentoml containerize executes injected RUN instructions during docker build, accessing build secrets and poisoning images.","categories":["Unclassified"],"product":"BentoML","vendor":"bentoml","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112264","source_modified_at":"2026-10-19T18:08:19.307Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"BentoML","vendor":"bentoml","versions":[{"version":"0","lessThanOrEqual":"1.4.39","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00218,"percentile":0.1167,"score_date":"2026-10-23"},"published_at":"2026-10-19T13:55:14.430Z","modified_at":"2026-10-19T18:08:19.307Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112264","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T18:08:19.307Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112264","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/geo-chen/oss/blob/main/BentoML.md","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/bentoml/BentoML/blob/v1.4.39/src/bentoml/_internal/container/frontend/dockerfile/templates/base.j2","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/bentoml/BentoML/blob/v1.4.39/src/bentoml/_internal/bento/build_config.py","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/bentoml/BentoML/blob/v1.4.39/src/bentoml/_internal/container/generate.py","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/bentoml/BentoML/blob/v1.4.39/src/bentoml/_internal/container/__init__.py","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/bentoml-through-1.4.39-dockerfile-instruction-injection-via-docker-env-keys","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-19T18:08:03.504973Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T18:08:19.307Z","content_hash":"ad9fbb30066c1036747e2617bc8ae65200589e157193c231e9914333eb09171d"}}
