An attacker could use this flaw to execute arbitrary code.","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","CWE-200"],"references":["https://access.redhat.com/errata/RHSA-2020:0729","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14893","https://github.com/FasterXML/jackson-databind/issues/2469","https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.bookkeeper.apache.org%3E","https://lists.apache.org/thread.html/rf1bbc0ea4a9f014cf94df9a12a6477d24a27f52741dbc87f2fd52ff2%40%3Cissues.geode.apache.org%3E"],"products":["fasterxml:jackson-databind","netapp:oncommand_api_services","netapp:steelstore_cloud_integrated_storage","oracle:goldengate_stream_analytics"],"source":"nvd","synced_at":"2026-10-19T21:02:53.949909883+00:00"},"epss":{"cve":"CVE-2019-14893","score":0.04091,"percentile":0.90654,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qmqc-x3r4-6v39","url":"https://osv.dev/vulnerability/GHSA-qmqc-x3r4-6v39","summary":"Polymorphic deserialization of malicious object in jackson-databind","modified":"2026-08-07T08:12:32.244710454Z","packages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.9.0 <2.9.10"],"fixed":["2.9.10"]}]}],"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).
