Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-59317 in the wild and no public exploit code.\n\nAffected product: Spring for Apache Kafka. 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-2026-59317/ (Markdown: https://insights.sbomify.com/CVE-2026-59317/index.md)","id":"CVE-2026-59317","markdown":"https://insights.sbomify.com/CVE-2026-59317/index.md","name":"CVE-2026-59317","record":{"aliases":["CLSA-2026-1792590657","GHSA-v648-fvf7-jrg2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Kafka library","requires_auth":"low_privilege","summary":"Attackers can cause denial of service in Spring for Apache Kafka by sending malformed headers that trigger infinite retry loops.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_for_apache_kafka","vendor":"vmware"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"DeadLetterPublishingRecovererFactory reads the retry_topic-original-timestamp header from an inbound ConsumerRecord and passes its raw bytes directly to new BigInteger(header.value()) with no length or format validation.\nSpring for Apache Kafka 4.1.0\nSpring for Apache Kafka 4.0.0 - 4.0.6\nSpring for Apache Kafka 3.0.0 - 3.3.16\nSpring for Apache Kafka 2.9.0 - 2.9.14\nSpring for Apache Kafka 2.8.12 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":"Denial of service in Spring for Apache Kafka","id":"CVE-2026-59317","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":"DefaultToolCallingManager Global Resolver Fallback Allows Unadvertised Tool Dispatch via Prompt Injection","id":"CVE-2026-59318"},"packages":[],"prev":{"headline":"Spring Authorization Server Default Consent Page is vulnerable to Cross-Site Scripting (XSS)","id":"CVE-2026-59316"},"products":["Spring for Apache Kafka"],"published":"2026-08-27","related":[{"cvss_score":6.5,"headline":"Server-side request forgery in Spring for Apache Kafka","id":"CVE-2026-59278","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":6.5,"headline":"In Spring for Apache Kafka, unbounded delegate cache keyed on user-controlled, potentially malicious selector header","id":"CVE-2026-41726","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":6.5,"headline":"In Spring for Apache Kafka, forged retry topic headers subvert retry routing and backoff behavior","id":"CVE-2026-41727","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":5.3,"headline":"Java Deserialization vulnerability in Spring-Kafka When Improperly Configured","id":"CVE-2023-34040","kev_date_added":null,"published":"2023-08-24"}],"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":"2026-08-28","vendors":["Spring"]},"summary":"Attackers can cause denial of service in Spring for Apache Kafka by sending malformed headers that trigger infinite retry loops.","url":"https://insights.sbomify.com/CVE-2026-59317/"}
