{"id":"CVE-2026-59888","aliases":["GHSA-3pjw-73gf-8qr5"],"url":"https://o3.security/vulnerability/CVE-2026-59888","summary":"jackson-databind: @JsonIgnore on a Record property is bypassed with a PropertyNamingStrategy","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.15.0 until 2.18.8, 2.21.4, and 3.1.4, Java Records using a PropertyNamingStrategy can bypass @JsonIgnore because POJOPropertiesCollector._removeUnwantedIgnorals() records an ignored component under its original implicit name before _renameUsing() applies the naming strategy, allowing the renamed JSON key to be assigned to the Record constructor parameter. This issue is fixed in versions 2.18.8, 2.21.4, and 3.1.4.","published":"2026-07-14T16:44:20.091Z","modified":"2026-08-12T16:09:53.007207Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00309,"percentile":0.2336,"asOf":"2026-09-06"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"2.18.8"},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"2.21.4"},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","fixedVersion":"3.1.4"}],"fix":{"url":"https://github.com/FasterXML/jackson-databind/commit/baa2cdf5ca2b2717fbb88d91955d69d8651df3e4","label":"FasterXML/jackson-databind@baa2cdf"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59888.json"},{"type":"ADVISORY","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-3pjw-73gf-8qr5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59888"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/baa2cdf5ca2b2717fbb88d91955d69d8651df3e4"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/c7c678360624da5bc7eed2152789fa522880db9d"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/pull/5974"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T16:09:53.007207Z"}}
