Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47859 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-2026-47859/ (Markdown: https://insights.sbomify.com/CVE-2026-47859/index.md)","id":"CVE-2026-47859","markdown":"https://insights.sbomify.com/CVE-2026-47859/index.md","name":"CVE-2026-47859","record":{"aliases":["GHSA-wh6x-77fw-hcqh"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Integration library","requires_auth":"low_privilege","summary":"Remote attackers can cause denial of service by sending crafted syslog frames with large octet counts, exhausting memory in Spring Integration applications.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_integration","vendor":"vmware"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"RFC6587SyslogDeserializer, used by the Spring Integration syslog TCP inbound adapter to decode RFC 6587 / RFC 5424 frames, trusts the sender-supplied octet count of an octet-counted frame and allocates a byte array of exactly that size with no upper bound.\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":"Unbounded memory allocation in RFC6587SyslogDeserializer (octet-counted framing) — remote DoS","id":"CVE-2026-47859","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Unbounded decompression of attacker-supplied compressed message bodies","id":"CVE-2026-47860"},"packages":[],"prev":{"headline":"live information startup mode is vulnerable for remote code execution","id":"CVE-2026-47858"},"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":"Remote attackers can cause denial of service by sending crafted syslog frames with large octet counts, exhausting memory in Spring Integration applications.","url":"https://insights.sbomify.com/CVE-2026-47859/"}
