Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required. NOTE: the vendor's position is that untrusted data is not an intended use case. The product's behavior will not be changed because some users rely on deserialization of trusted data.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-1000027","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-579669626","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-582313417","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-744519525","https://raw.githubusercontent.com/distributedweaknessfiling/cvelist/master/2016/1000xxx/CVE-2016-1000027.json"],"products":["vmware:spring_framework"],"source":"nvd","synced_at":"2026-10-19T21:01:01.339895972+00:00"},"epss":{"cve":"CVE-2016-1000027","score":0.33179,"percentile":0.98354,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4wrc-f8pq-fpqp","url":"https://osv.dev/vulnerability/GHSA-4wrc-f8pq-fpqp","summary":"Pivotal Spring Framework contains unsafe Java deserialization methods","modified":"2026-09-10T03:49:19.715346399Z","packages":[{"ecosystem":"Maven","name":"org.springframework:spring-web","purl":"pkg:maven/org.springframework/spring-web","ranges":["<6.0.0"],"fixed":["6.0.0"]}]}],"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).
