Jackson fixed this vulnerability by blacklisting known \"deserialization gadgets\". Spring Batch configures Jackson with global default typing enabled which means that through the previous exploit, arbitrary code could be executed if all of the following is true: * Spring Batch's Jackson support is being leveraged to serialize a job's ExecutionContext. * A malicious user gains write access to the data store used by the JobRepository (where the data to be deserialized is stored). In order to protect against this type of attack, Jackson prevents a set of untrusted gadget classes from being deserialized. Spring Batch should be proactive against blocking unknown \"deserialization gadgets\" when enabling default typing.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-502"],"references":["https://tanzu.vmware.com/security/cve-2020-5411","https://tanzu.vmware.com/security/cve-2020-5411"],"products":["broadcom:spring_batch"],"source":"nvd","synced_at":"2026-10-19T21:05:42.039641217+00:00"},"epss":{"cve":"CVE-2020-5411","score":0.01712,"percentile":0.77376,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4ph4-q9r5-6wm6","url":"https://osv.dev/vulnerability/GHSA-4ph4-q9r5-6wm6","summary":"Deserialization of Untrusted Data in Spring Batch","modified":"2023-11-08T04:03:55.467571Z","packages":[{"ecosystem":"Maven","name":"org.springframework.batch:spring-batch-core","purl":"pkg:maven/org.springframework.batch/spring-batch-core","ranges":[">=4.0.0 <4.2.3"],"fixed":["4.2.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
