Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47856 in the wild and no public exploit code.\n\nAffected product: Spring Integration. 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-2026-47856/ (Markdown: https://insights.sbomify.com/CVE-2026-47856/index.md)","id":"CVE-2026-47856","markdown":"https://insights.sbomify.com/CVE-2026-47856/index.md","name":"CVE-2026-47856","record":{"aliases":["CLEANSTART-2026-DC84124","CLSA-2026-1789669141","GHSA-647v-4254-wp99"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Integration library","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution by sending crafted messages with malicious type headers to Spring Integration applications.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_integration","vendor":"vmware"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Spring Integration's JSON to object conversion uses the json__TypeId__ header to choose the deserialization target type, and resolves that header value to a class with ClassUtils.forName and no type/package allow-list.\nSpring Integration 7.1.0\nSpring Integration 7.0.0 - 7.0.5\nSpring Integration 6.5.0 - 6.5.10\nSpring Integration 6.4.0 - 6.4.12\nSpring Integration 5.5.21 and earlier","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"JsonToObjectTransformer resolves the json__TypeId__ message header to an arbitrary class without an allow-list","id":"CVE-2026-47856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Reactor Core windowTimeout fair-backpressure stream hang due to 20-bit index wrap-around","id":"CVE-2026-47857"},"packages":[],"prev":{"headline":"Predictable cache directory location allows local ONNX model substitution in Spring AI","id":"CVE-2026-47852"},"products":["Spring Integration"],"published":"2026-08-26","related":[{"cvss_score":8.2,"headline":"fluxTransform shared RequestMessageHolder causes cross-message header leakage under async fluxFunction","id":"CVE-2026-59324","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":8,"headline":"Deserialization allow-list silently bypassed: setBeanClassLoader replaces deserializer but mapper keeps stale reference","id":"CVE-2026-59307","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":7.1,"headline":"Spring Integration File Support: FTP/SFTP/SMB server can write arbitrary files anywhere on the client filesystem","id":"CVE-2026-40987","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":6.8,"headline":"Fixed predictable /tmp/ziptransformer work directory enables symlink pre-creation","id":"CVE-2026-59311","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":6.6,"headline":"SMB minimum protocol dialect defaults to SMB1","id":"CVE-2026-59293","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":6.5,"headline":"Unbounded decompression in UnZipTransformer enables zip-bomb DoS","id":"CVE-2026-59274","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":6.4,"headline":"Unsafe Java deserialization in SerializingHttpMessageConverter — remote code execution","id":"CVE-2026-47864","kev_date_added":null,"published":"2026-08-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Spring"]},"summary":"Attackers can achieve remote code execution by sending crafted messages with malicious type headers to Spring Integration applications.","url":"https://insights.sbomify.com/CVE-2026-47856/"}
