{"cve":"CVE-2026-54518","nvd":{"published":"2026-06-23T22:16:32.073","modified":"2026-10-25T23:10:00.167","status":"Analyzed","description":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, UnwrappedPropertyHandler.processUnwrappedCreatorProperties() replays buffered JSON into creator parameters but never consults prop.visibleInView(activeView). The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses that check, so a constructor parameter annotated with both @JsonView(AdminView.class) and @JsonUnwrapped is populated from attacker JSON even when a more restrictive view is active. This vulnerability is fixed in 2.21.4 and 3.1.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-863"],"references":["https://github.com/FasterXML/jackson-databind/commit/721fa07ebbd4aab4a659a1a68940878315c3e341","https://github.com/FasterXML/jackson-databind/commit/d633bc038f200c1397c07f1a2b46f58e72c91eea","https://github.com/FasterXML/jackson-databind/pull/5971","https://github.com/FasterXML/jackson-databind/pull/5973","https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-rcqc-6cw3-h962"],"products":["fasterxml:jackson-databind"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54518","score":0.00354,"percentile":0.28861,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rcqc-6cw3-h962","url":"https://osv.dev/vulnerability/GHSA-rcqc-6cw3-h962","summary":"jackson-databind has a @JsonView bypass for unwrapped creator parameters","modified":"2026-09-10T03:50:50.530979931Z","packages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.21.0 <2.21.4"],"fixed":["2.21.4"]},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","purl":"pkg:maven/tools.jackson.core/jackson-databind","ranges":[">=3.0.0 <3.1.4"],"fixed":["3.1.4"]}]}],"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).
