An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47878 in the wild and no public exploit code.\n\nAffected product: Spring Batch. 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-2026-47878/ (Markdown: https://insights.sbomify.com/CVE-2026-47878/index.md)","id":"CVE-2026-47878","markdown":"https://insights.sbomify.com/CVE-2026-47878/index.md","name":"CVE-2026-47878","record":{"aliases":["CLSA-2026-1791375028","GHSA-2pwq-qhmm-3vg8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring Batch library","requires_auth":"none","summary":"Attackers can execute arbitrary code via unsafe Java deserialization in Spring Batch's default JDBC job repository serializer.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_batch","vendor":"broadcom"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"DefaultExecutionContextSerializer, used by default in Spring Batch's JDBC job repository, passes Base64-decoded bytes directly to ObjectInputStream.readObject() without an ObjectInputFilter that restricts types to a trusted class allowlist.\nSpring Batch 6.0.0 - 6.0.4\nSpring Batch 5.2.6 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":"Unsafe Java deserialization in DefaultExecutionContextSerializer without class allowlist","id":"CVE-2026-47878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Spring Cloud Gateway SSRF and native file access with gRPC","id":"CVE-2026-47879"},"packages":[],"prev":{"headline":"Spring Security Authorization Server Default Consent Page is vulnerable to Cross-Site Scripting (XSS)","id":"CVE-2026-47877"},"products":["Spring Batch"],"published":"2026-08-27","related":[{"cvss_score":9.8,"headline":"Spring Batch XML External Entity Injection (XXE)","id":"CVE-2019-3774","kev_date_added":null,"published":"2019-01-18"},{"cvss_score":8.1,"headline":"Jackson Configuration Allows Code Execution with Unknown \"Serialization Gadgets\"","id":"CVE-2020-5411","kev_date_added":null,"published":"2020-06-11"},{"cvss_score":5.9,"headline":"Denial of Service in Spring Batch FlatFileItemReader via Malformed Input File","id":"CVE-2026-47881","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":5.6,"headline":"JobParameterDeserializer bypasses the trusted-type allowlist","id":"CVE-2026-47875","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 execute arbitrary code via unsafe Java deserialization in Spring Batch's default JDBC job repository serializer.","url":"https://insights.sbomify.com/CVE-2026-47878/"}
